MIC3201YME

LED Driver IC Overview

The MIC3201YME is a hysteretic step-down, constant-current High-Brightness LED driver capable of driving up to four 1A LEDs. It operates with an input voltage range from 6V to 20V and features a high switching frequency of up to 1MHz. The device utilizes high-side current sensing with an on-chip amplifier to deliver LED current with ±5% accuracy. An external resistor sets the output current, while a dedicated PWM input enables wide-range pulsed dimming. It functions within a junction temperature range of -40°C to +125°C and is housed in an 8-pin ePAD SOIC package.
