MIC2287BD5-TR

LED Driver IC Overview

The MIC2287BD5-TR is a synchronous step-down DC-DC converter manufactured by Microchip Technology, designed for portable and low-power applications. It operates within an input voltage range of 2.5V to 10V and delivers up to 750mA output current. The device features a fixed switching frequency of 1.2MHz and includes overvoltage protection (OVP). Packaged in an 8-pin MLF (2x2mm) or TSOT-23-5 format, it functions efficiently across temperatures from -40°C to +125°C.

LED Driver IC Feature Summary

• Synchronous buck topology for high efficiency
• Integrated overvoltage protection circuitry
• Fixed 1.2MHz switching frequency

LED Driver IC Applications

• Portable electronic devices
• Low-power system power management
• Battery-powered equipment

LED Driver IC Procurement Notes

Verify the specific package variant (MLF vs. TSOT-23-5) against design requirements, as datasheet references vary. Confirm the manufacturer origin (Microchip vs. Micrel legacy) for supply chain consistency. Ensure the OVP threshold matches the load specifications before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component for space-constrained designs requiring synchronous rectification. The 1.2MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 750mA current limit meets the peak load demands of the target application without triggering thermal shutdown.

LED Driver IC Part Context

This part belongs to the MIC2287 family of LED drivers and DC-DC converters. While often categorized with LED lighting solutions due to constant-current variants, the BD5 suffix typically denotes the standard buck regulator configuration. It shares architectural similarities with the MIC3287 series but differs in specific protection thresholds and package options.

LED Driver IC Replacement Considerations

MIC2287-15YML-TR: Similar form factor but different OVP rating. MIC3287BD5-TR: Higher voltage tolerance variant. Verify pin compatibility and electrical parameters before substitution.
