The MP2488 is a fixed frequency step-down switching regulator to deliver a constant current of up to 2A to high power LEDs. It integrat a high-side, high voltage power MOSFET with a current limit of 3.2A. The wide 4.5V to 55V input range accommodat 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 rponse, easy compensation and accurate LED current regulation. The switching frequency is programmable with an external ristor up to 200kHz, which can prevent EMI (Electromagnetic Interference) noise problems. The thermal shut down provid reliable, fault tolerant operations. A 12μA quicent current in shutdown mode allows its use in batterowered applications. The MP2488 is available in all 3x3mm 10-pin QFN and SOIC8 with exposed pad packag.
