MIC2287-15BML-TR

LED Driver IC Overview

The MIC2287-15BML-TR is a white LED driver IC manufactured by Microchip Technology, designed for high-efficiency lighting applications. It operates as a DC-DC step-up (boost) regulator with a fixed switching frequency of 1.2MHz. The device supports analog and PWM dimming control methods to adjust brightness levels precisely. It features an internal switch capable of delivering up to 750mA of output current. The unit is housed in an 8-MLF® (2x2mm) surface-mount package, providing a compact solution for space-constrained designs. It functions within a supply voltage range of 2.5V to 10V and includes overvoltage protection rated at 15V.

LED Driver IC Feature Summary

LED Driver IC Procurement Notes

Verify the specific suffix 'BML' against the manufacturer's latest datasheet to confirm pinout and thermal pad configuration, as variations exist within the MIC2287 family. Ensure the ordering code matches the required tape-and-reel quantity. Cross-reference the RoHS status and MSL rating with current environmental compliance documents before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component when a small footprint is critical for portable electronics requiring high-brightness LED driving. The 1.2MHz frequency allows for smaller external inductors compared to lower-frequency alternatives. Consider the 750mA current limit and 15V OVP when designing for series LED strings. Verify that the input voltage range of 2.5V to 10V aligns with the system power supply architecture.

LED Driver IC Part Context

This part belongs to the MIC2287 family of constant-frequency PWM white LED drivers from Microchip Technology. It succeeds earlier Micrel designs following the company acquisition. The device is engineered to replace discrete solutions, integrating the controller, switch, and protection circuits into a single small package. It is commonly used in consumer electronics where size and efficiency are paramount.

LED Driver IC Replacement Considerations

MIC2287-15YML-TR is a parameter-equivalent substitute within the same family. Verify package compatibility and ensure the 'YML' suffix does not indicate different thermal or electrical characteristics compared to the 'BML' variant before substitution.
