MIC2870YFT-T5

LED Driver IC Overview

The MIC2870YFT-T5 is a dual-channel high-brightness flash LED driver manufactured by Microchip Technology. It utilizes a boost (step-up) DC-DC regulator topology to drive LEDs, supporting an input voltage range of 2.7V to 5V and delivering up to 1.5A per channel. The device operates with a fixed switching frequency of 2MHz and features I²C dimming control for precise brightness adjustment. It is housed in a compact 16-TQFN package.

LED Driver IC Feature Summary

• Dual-channel output configuration capable of driving high-brightness LEDs independently.
• Integrated I²C interface for digital dimming and operational control.
• Boost converter topology designed for efficient step-up regulation from low input voltages.

LED Driver IC Applications

• Mobile device camera flash systems
• High-intensity LED lighting modules
• Portable electronic devices requiring regulated LED power

LED Driver IC Procurement Notes

Verify the specific suffix 'T5' against current Microchip documentation to confirm packaging and availability status, as component lifecycle stages may vary. Ensure compatibility with existing PCB footprints for the 16-TQFN package before procurement. Cross-reference part numbers with official distributors to avoid obsolete stock.

LED Driver IC Selection Notes

Select this component when dual-channel LED control with digital I²C dimming is required. The 2MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Ensure the application input voltage falls within the 2.7V to 5V range and that the thermal performance of the TQFN package suits the enclosure constraints.
