MP2488DN Datasheet | Monolithic Power Systems

The Future of Analog IC Technology DESCRIPTION The MP2488 is a fixed frequency step-down switching regulator to deliver a constant current of up to 2A to high power LEDs. It integrates a high-side, high voltage power MOSFET with a current limit of 3.2A. The wide 4.5V to 55V input range acmodates a variety of step-down applications, making it ideal for automotive, industry and general lighting applications. Peak current mode control and 200mV reference are applied for fast loop response, easy pensation and accurate LED current regulation. The switching frequency is programmable with an external resistor up to 200kHz, which can prevent EMI (Electromagnetic Interference) noise problems....
