MCHPMIC2287-24YML-TR
Overview
The MIC2287-24YML-TR is a high-power-density, 1.2MHz PWM step-up DC-DC regulator specifically designed to drive series LEDs. It features an internal 750mA switch and integrated 24V overvoltage protection, allowing it to drive up to six LEDs in series from a single-cell Li-ion battery.
Why Choose This Part
The high 1.2MHz switching frequency allows for the use of very small inductors and capacitors, saving PCB real estate. It offers flexible dimming options via both analog and PWM signals while maintaining low 2500uA operating current and 0.1uA shutdown current for extended battery life.
Applications
Key Specifications
Getting Started
Designers should prioritize low-ESR ceramic capacitors and place the input capacitor as close as possible to the VIN pin. Ensure the feedback resistor network is calculated for the target LED current, and refer to the MLF-8 package layout guidelines to manage thermal dissipation through the exposed pad.
