MP2488

200kHz, 55V Input, 2A

High Power LED Driver

The Future of Analog IC Technology

DESCRIPTION

FEATURES

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 accommodates 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

compensation and accurate LED current

regulation. The switching frequency is

programmable with an external resistor up to
