MP4013GS

PMIC - LED Drivers

The MP4013GS is an integrated LED driver from Monolithic Power Systems (MPS) that is designed to drive high-brightness LED strings from a nominal 12V (10V-14V) input drive voltage. The LED driver operates with amplified voltage and current conversion efficiency, minimal thermal stress, and near unity power factor. The MP4013GS is a linear driver, meaning that the LED current output will remain constant, regardless of fluctuations in the input voltage. It is protected against over-voltage and over-current conditions, making it a high-reliability, low-cost LED driver.

Application Fields

The MP4013GS LED driver is suitable for applications such as LED lighting, LED illumination, LED billboards, LED decor, LED signs, LED display and LED panels. The LED driver can also be used in automotive and industrial lighting. The MP4013GS LED driver is a cost-effective solution to power LED strings in the new generation of LED lights such as retrofit bulbs, tube lights and wall washers. The MP4013GS LED driver can reduce the number of external components needed and provide high efficiency, low heat and good thermal management for long lasting LED performance.

Working Principle

The MP4013GS is a linear LED driver that uses a constant current method to provide constant current output. The working principle of the MP4013GS is based on the open-loop topology. The input voltage from the AC power source is stepped down by the power converter and is then fed to the current regulator. The current regulator uses pulse-width modulation (PWM) to control the output current. The output current is then fed to the LED string and is monitored and regulated by the current regulator to ensure that the output current remains within the specified range.

The MP4013GS LED driver uses an error amplifier to maintain good regulation and accuracy. The error amplifier is a circuit that compares the voltage across the LED string with the dc reference voltage and generates an error signal that is used to adjust the duty cycle of the PWM. The duty cycle is adjusted to maintain the current across the LED string within the specified range. The MP4013GS LED driver also includes temperature and overvoltage protection and is compatible with dimming technologies such as 0-10V dimming and PWM dimming.

Conclusion

To sum up, the MP4013GS LED driver is a linear LED driver that is suitable for high-brightness LED applications. The MP4013GS LED driver can be used to reduce the number of external components and provide high efficiency, low heat and good thermal management for long lasting LED performance. It also has protection against over-voltage and over-current, making it an ideal solution for high-reliability, low-cost LED driver applications.
