MP2480
MP2480 is 3A High Power LED Driver manufactured by Monolithic Power Systems.
The Future of Analog IC Technology
DESCRIPTION
The MP2480 is step-down switching regulator that delivers a constant current of up to 3A to high-power LEDs. It integrates a high-side, high-voltage power MOSFET with a current limit of 4.3A. The wide 5V to 36V input range acmodates a variety of step-down applications, making it ideal for general lighting and LCD backlighting applications. Hysteretic current-mode control helps provide for a very fast response, which makes the 20kHz dimming frequency possible. MPS’s proprietary feedback control minimizes the number of external ponents while delivering an LED current with a typical accuracy of ±3%.
The switching frequency goes up to 2MHz,...
