How do constant current LED drivers maintain steady current?

The following are the core mechanisms and technical implementation methods of the constant current LED driver to maintain a stable current, combined with its working principle and key components for explanation:

1. The basic principle of constant current drive

Negative feedback control mechanism

The constant current driver monitors the LED current in real time through the built-in feedback loop (usually obtains the voltage signal through the series sampling resistor) and compares it with the preset reference value.

When the current deviation is detected, the driver chip automatically adjusts the output (such as adjusting the MOSFET switch duty cycle or linear impedance) to return the current to the set value.

Linear constant current and switching constant current technology

Linear constant current: Directly control the current by adjusting the impedance of the transistor or MOSFET, with a simple structure but low efficiency (suitable for low voltage difference scenarios).

Switching constant current: Using the buck, boost or buck-boost topology, the energy transmission is adjusted through high-frequency switching, and the efficiency can reach 80%-90%.

2. Key technologies for maintaining current stability

Precision current sampling and compensation

Use high-precision sampling resistors (such as 0.1Ω-1Ω) to convert the current into a voltage signal, and compare the reference voltage through the error amplifier to achieve a constant current accuracy of ±1%.

Some chips integrate input voltage compensation function to prevent grid fluctuations from affecting output.

Temperature management design

Built-in over-temperature regulation (OTP) function, automatically reducing current when chip temperature exceeds threshold to avoid thermal runaway.

Improve system stability by reducing heat dissipation design (such as high-voltage linear solution).

Anti-interference and protection mechanism

Add filter circuit to input stage to suppress surge voltage and electromagnetic interference (EMI).

Integrated short circuit protection, open circuit protection and reverse voltage protection to prevent abnormal working conditions from damaging LED or driver.

III. Typical application scenarios and dimming function

Dynamic dimming implementation

PWM dimming: Control the average current by adjusting the duty cycle of the switching frequency to avoid color deviation (frequency is usually >100Hz).

Analog dimming: Directly adjust the reference voltage value to change the output current, suitable for scenes without flicker requirements.

Multi-channel intelligent control

High-end chips support multiple independent constant current outputs, each of which can be programmed separately to meet complex lighting needs (such as RGB mixed light).

IV. Advantages and limitations

Advantages:

Ensure LED brightness consistency and long life (avoid rapid light decay caused by overcurrent).

Adapt to wide input voltage range (such as 5V-60V), compatible with a variety of power supply environments.

Limitations:

The linear constant current solution generates a lot of heat and requires additional heat dissipation design; the switch solution has a high cost.

Reference design example

H6901B boost chip: supports 12V-100V input, sets current through external resistors, and has an efficiency of >90%.

SM2082EAS linear chip: built-in over-temperature derating function, suitable for low-voltage applications such as LED light strips.

If you need a specific circuit diagram or selection suggestions, you can further analyze the voltage, power and dimming requirements of the application scenario.

Three Key Concepts to Quickly Understand PMOS in MOSFETs

To understand PMOS, we first need to know: what is MOS? MOS stands for Metal-Oxide-Semiconductor Field-Effect Transistor. As the name suggests, M stands for metal, O for oxide, and S for semiconductor. In summary, it is a type of semiconductor device that uses metal and oxide layers.

In electronic circuits, metals are used when conductivity is needed, and insulating materials are used when conductivity is not needed. So, how do we get something that can both conduct and not conduct electricity? The answer is semiconductors.

Today, we are discussing MOS, which is one type of semiconductor. MOS has semiconductor properties that allow it to conduct electricity at times and insulate at others, acting as a switch in the circuit. PMOS is a type of MOS distinguished from NMOS by the channel type.

PMOS Working Principle

（Electronic switch）

Since PMOS functions as a switch, we need to understand how it turns on and off. First, we need to know that PMOS has an n-type substrate and a p-type channel. The direction of the current is from the source to the drain, carried by the flow of holes.

（Low-Level Drive）

PMOS is a low-level drive circuit, meaning that when the gate-source voltage (Vgs) is below a certain value, it will turn on. This is suitable when the source is connected to VCC (high-side drive). On the other hand, when Vgs is greater than or equal to a certain value, PMOS will turn off. In this way, the gate voltage acts like an invisible hand that controls whether PMOS is on or off by controlling the voltage level, thereby forming or cutting off the current in the circuit. Isn't it fascinating?

Advantages of PMOS

As one of the key players in MOSFETs, PMOS has irreplaceable functions and advantages.

1、Low Noise: PMOS has lower noise than NMOS, making it suitable for use in analog circuits.

2、High Threshold Voltage: PMOS typically has a higher threshold voltage, providing strong interference resistance.

3、Low Power Consumption: In a static state, PMOS has low current loss.

Applications of PMOS in Different Industries

（Large electronic demand households）

Thanks to its advantages, PMOS has penetrated various industries, and you can find its presence in many devices you use every day. In terms of market applications, the number one sector is consumer electronics. Devices like smartphones and tablets, which you are likely familiar with, all feature PMOS. PMOS is mainly used in key components such as microprocessors, memory chips, and display driver circuits, helping these devices maintain long battery life.

The second sector is computer networks, including processors, memory, and routers. PMOS plays roles in data storage, logical computation, and signal regulation. Third on the list are network communications, industrial control, automotive electronics, and power equipment. The demand for MOSFETs in these industries is also high, especially in automotive electronics, which now rivals consumer electronics in MOSFET demand.

Future Development of PMOS

The future development of PMOS transistors will focus on improving performance, reducing power consumption, increasing integration, and expanding application areas. New materials, advanced manufacturing processes, 3D integration technologies, and integration with emerging technologies like artificial intelligence and quantum computing will be the main directions for PMOS development.

Slide Switches: Waterproof and Dustproof Design for Extreme Environments

In many high-power applications, a slide switch is not merely a simple switching element but must be capable of providing higher-level protection functionalities, especially in the event of overloads, short circuits, and other abnormal situations. As electronic devices become increasingly power-intensive, the demands on switches are growing. Overload protection and short circuit protection have become key aspects of switch design. This article will delve into the overload protection and short circuit protection design of slide switches in high-power applications, discussing their working principles, design methodologies, and practical applications, along with specific examples.

1. Challenges of Slide Switches in High-Power Applications

In high-power applications, equipment is required to handle large currents and voltages, which demands that the switch not only bear high-power loads but also offer protection capabilities to handle electrical anomalies. Without overload or short-circuit protection, a system could be damaged, cause electrical fires, or even result in personal injury.

For example, in automotive electrical systems, power control devices, industrial machinery, and high-power consumer electronics, switches must effectively prevent excessive current flow or quickly interrupt the circuit in the case of a short circuit, ensuring the safety of the system.

2. Basic Principles of Overload and Short Circuit Protection

1. Overload Protection

Overload occurs when the current exceeds the device or circuit's safe rating. Prolonged overload may lead to component overheating, failure, or even fire. Overload protection in slide switches is typically achieved in the following ways:

Thermal Protection: A common overload protection method involves thermal elements (such as thermal fuses). These elements heat up with increasing current, and when the current exceeds a certain threshold, the temperature rises, causing the fuse to blow and cutting the current to prevent further damage.

Overload Contact Design: Some slide switches incorporate self-resetting overload contacts that prevent contact damage due to overload. In such cases, the switch contacts may physically deform, such as bending or melting, thus automatically disconnecting the circuit.

Electronic Overload Protection: In modern high-power systems, electronic circuits (ICs) are increasingly being used for overload protection. These ICs can monitor the current in real time and disconnect the circuit through components like MOSFETs or relays when an overload occurs.

2. Short Circuit Protection

A short circuit occurs when current finds a low-resistance path in the circuit, creating abnormally high currents that can severely damage electrical components. Short circuit protection aims to quickly identify a short circuit and disconnect the current, preventing damage to the system. Short circuit protection is typically achieved in the following ways:

Fuses: Fuses are commonly used for short circuit protection. When the current exceeds a certain value, the fuse will blow, cutting off the circuit to protect the components from damage.

Circuit Breakers: Similar to fuses, circuit breakers disconnect the circuit in the event of a short circuit. However, unlike fuses, circuit breakers can reset after a fault occurs. When used in combination with slide switches, circuit breakers can quickly respond to a short circuit and provide secondary protection.

Electronic Current Limiting: Electronic current limiting technology is increasingly employed in modern switch systems to protect against short circuits. By incorporating current sensing circuits, the system can reduce the current or cut off the circuit immediately upon detection of a short circuit.

3. Overload and Short Circuit Protection in Slide Switches

In high-power applications, slide switches need to integrate robust overload and short circuit protection features. The following are design strategies for achieving this:

1. Overload Protection Design

High-Temperature Materials: In high-power applications, slide switches must use materials that can withstand high temperatures, such as high-temperature plastics (e.g., PPS, PTFE) and ceramics, to ensure that the switch does not fail due to material degradation under overload conditions.

Thermal Fuses: Some slide switches incorporate thermal fuses inside. When an overload occurs, the fuse blows to disconnect the current and prevent further damage. Thermal fuses are usually designed to be replaceable for easy maintenance.

Thermal Protection and Self-Reset Functionality: Some high-power devices incorporate self-resetting thermal protection in slide switches. Even if the thermal protection element blows and disconnects the circuit, the switch will automatically reset once the temperature normalizes, allowing current to flow again. This design is suitable for devices that experience intermittent heavy loads.

2. Short Circuit Protection Design

Built-in Fuses: To prevent damage from short circuits, slide switches can incorporate micro fuses inside. These fuses will quickly blow when a short circuit occurs, protecting the switch and other electrical components.

Electronic Monitoring Circuits: High-end slide switches often include electronic monitoring circuits that track the current in real-time. Upon detection of a short circuit, the system will immediately disconnect the circuit through components like MOSFETs or relays, providing protection.

Mechanical Circuit Breakers: In industrial control systems, slide switches are often paired with mechanical circuit breakers to ensure that not only does the switch disconnect the circuit in the event of a short circuit, but users can also restore normal operation by resetting the breaker after the fault is cleared.

4. Practical Applications of Overload and Short Circuit Protection

1. Automotive Electrical Systems

In automotive electrical systems, slide switches are commonly used to control various electrical devices, such as lighting systems, onboard power supplies, and air conditioning systems. These systems can have heavy current loads, so switches need to offer both overload and short circuit protection. For instance, in high-power automotive devices (like onboard refrigerators or charging systems), overload protection is essential. If the current exceeds the safe threshold, the switch should disconnect the power to prevent the battery from overheating or the device from being damaged.

By utilizing high-temperature materials in the casing and integrating thermal fuses, the slide switch can cut off the current in the event of an overload. Additionally, electronic current-limiting technology helps reduce current during a short circuit, preventing further damage.

2. Industrial Machinery

In industrial automation, slide switches are often used to control high-power equipment like motors, hydraulic pumps, and industrial conveyors. These devices can experience abnormal current conditions due to overload, short circuits, or mechanical failure. Therefore, overload and short circuit protection are critical.

For example, in some industrial applications, slide switches integrate circuit breakers and thermal protection elements. When overload occurs, the thermal protection element will disconnect the current, preventing the equipment from overheating. At the same time, the circuit breaker will quickly disconnect the circuit in the event of a short circuit, preventing fire hazards or damage to the equipment.

5. Conclusion: Ensuring Safety in High-Power Applications with Slide Switches

In high-power applications, slide switches are not just tools for controlling current; their overload and short circuit protection capabilities are vital for ensuring the system’s stability and safety. Through the use of high-temperature materials, thermal protection mechanisms, electronic monitoring circuits, and safety fuses, slide switches can effectively prevent damage caused by overloads and short circuits, thereby extending the service life of the equipment and safeguarding users.

As the demand for higher power and reliability increases in industrial, automotive, and consumer electronics applications, the design of slide switches will continue to evolve toward more refined and intelligent protection features. This will provide greater safety for various devices, ensuring reliable operation in high-power applications.

What Is Three Phase IGBT Inverter？

Hello everyone, we all know that there are three types of inverters, namely single-phase inverters, split-phase inverters and three-phase inverters. The biggest difference between these three inverters is the difference in voltage phase. When learning about inverters, some customers have doubts about IGBT. Today we will share with you what IGBT is and their functions.

First of all, we need to know that IGBT is an insulated gate bipolar transistor, which is a composite fully-controlled voltage-driven power semiconductor device composed of bipolar transistor and an insulated gate field effect transistor. Therefore, its advantages are the high input impedance of MOSFET and the low turn-on voltage drop of GTR. At the same time, the GTR saturation voltage decreases, the current carrying density is large, but the driving current is large; the MOSFET driving power is small, the switching speed is fast, but the conduction voltage drop is large, and the current carrying density is small.

When our machine has a power greater than 7kw, we will choose IGBT technology. We are keen to provide customers with the highest quality products, the best user experience and the most considerate service.
