MIC2287C-15BML-TR

LED Driver IC Overview

The MIC2287C-15BML-TR is a 1.2 MHz pulse width modulated (PWM) boost-switching regulator optimized for constant-current white LED driver applications. It features an internal switch rated for 750 mA, operating within a supply voltage range of 2.5 V to 10 V. The device provides adjustable output voltage and includes a 15 V overvoltage protection feature. Packaged in an 8-pin MLF® (2x2 mm) lead-free surface-mount package, it supports analog and PWM dimming control with a wide operating temperature range from -40°C to +125°C.

LED Driver IC Procurement Notes

Verify the specific suffix 'C' and '15' against the official Microchip datasheet to confirm the 15V OVP rating and C-grade temperature specifications. Ensure the 8-MLF package footprint matches the design layout. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component for designs requiring a compact solution for white LED arrays driven by a single channel. The 750 mA internal switch limits suitability for high-power applications exceeding this current threshold. Consider the 1.2 MHz switching frequency for inductor size optimization relative to lower-frequency alternatives. Verify input voltage compatibility within the 2.5 V to 10 V range.
