Hot-selling and scarce MP2488DN-LF-Z 200kHz, 55V Input, 2A High Power LED Driver SOP-8

Product Descriptions

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  200kHz, which can prevent EMI  (Electromagnetic Interference) noise problems.  The thermal shut down provides reliable, fault  tolerant operations. A 12µA quiescent current in  shutdown mode allows its use in batterypowered applications. ​

The MP2488 is available in small 3x3mm 10-pin  QFN and SOIC8 with exposed pad packages.
