MIC2292-34YML-TR

LED Driver IC Overview

The MIC2292-34YML-TR is a white LED driver IC featuring an integrated boost DC-DC converter. It operates with a switching frequency of 1.6MHz and supports input voltages from 2.5V to 10V. The device provides a maximum switch current of 750mA and includes a 34V overvoltage protection (OVP) feature. It offers analog and PWM dimming capabilities for backlight applications. The component is housed in an 8-MLF package measuring 2x2mm.

LED Driver IC Feature Summary

• Integrates a high-efficiency boost converter with internal power switch
• Provides precise constant current regulation for white LEDs
• Includes 34V output overvoltage protection for circuit safety
• Supports both analog and pulse-width modulation dimming methods

LED Driver IC Applications

• LCD backlight drivers for portable devices
• White LED lighting systems
• Mobile phone displays
• Camera flash circuits

LED Driver IC Procurement Notes

Verify the specific suffix '34' indicates the 34V OVP threshold, as other variants exist within the MIC2292 family. Confirm the MLF-8 package dimensions match the design footprint. Ensure compatibility with the required 1.6MHz switching frequency for inductor selection. Check RoHS compliance status if environmental regulations apply to the final assembly.

LED Driver IC Selection Notes

Select this part when a compact solution for single-string white LED driving is required. The 750mA switch current rating suits medium-brightness backlighting needs. The 1.6MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 34V OVP limit when designing for higher voltage LED strings or transient conditions.

LED Driver IC Part Context

This component belongs to the MIC2292 series of LED lighting drivers manufactured by Microchip Technology. It is designed specifically for regulating current in white LED arrays. The series typically features integrated switches to minimize external component count. Variants differ primarily by their overvoltage protection thresholds and packaging options.

LED Driver IC Replacement Considerations

MIC2292-15YML-TR is a parameter-equivalent alternative within the same family, differing in overvoltage protection specifications.
