MIC2287C-34YML-TR

LED Driver IC Overview

The MIC2287C-34YML-TR is a 1.2 MHz PWM boost-switching regulator optimized for constant-current white LED driver applications. It operates within an input voltage range of 2.5 V to 10 V and delivers up to 750 mA output current. The device features a 34 V overvoltage protection (OVP) threshold, adjustable output voltage, and supports both analog and PWM dimming. It functions reliably across an extended temperature range from -40°C to +125°C and is housed in an 8-pin MLF® (2x2 mm) package.

LED Driver IC Feature Summary

• Integrated 34 V overvoltage protection safeguards connected LEDs against transient voltage spikes.
• Supports dual dimming methods including high-frequency PWM and analog control for flexible brightness management.
• Compact 2 mm x 2 mm MLF® package enables space-constrained PCB layouts.

LED Driver IC Applications

• Portable electronic devices requiring white LED illumination
• Backlight systems for mobile displays
• Indicator lighting in consumer electronics

LED Driver IC Procurement Notes

Verify the specific suffix '34YML' confirms the 34 V OVP rating and MLF-8 package variant. Ensure compatibility with your board's thermal design for the exposed pad. Confirm RoHS compliance status via the manufacturer's latest documentation before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component when a 34 V OVP limit is required for the LED string. Compare against other MIC2287 variants with different OVP ratings if the application voltage differs. Ensure the 1.2 MHz switching frequency aligns with available passive component sizes and EMI constraints.

LED Driver IC Part Context

This part belongs to the MIC2287 family of single-channel white LED drivers. Variants differ primarily by their overvoltage protection thresholds, such as 15 V or 24 V options. All members share the same core topology and control interface, differing mainly in protection specifications and package availability.

LED Driver IC Replacement Considerations

Direct substitutes include MIC2287-15YML-TR and MIC2287-24YML-TR. Verify that the lower OVP ratings of these alternatives do not exceed the maximum voltage tolerance of the target LED array.
