产品说明:
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代孕费用-【最出色的2018最新技术10SJ】早教频道. Peak current mode control and 200mV reference are applied for fast loop response, easycompensation 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 battery-powered applications.
