MP3309GQG-Z

LED Driver IC Overview

The MP3309GQG-Z is a synchronous boost DC-DC converter designed for white LED backlighting. It operates with an input voltage range of 2.7V to 5.5V and delivers up to 1.5A output current at a fixed switching frequency of 640kHz. The device supports analog and PWM dimming methods and provides a maximum output voltage of 35V. Packaged in a compact 10-QFN (1.4x1.8mm) format, it functions within a junction temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Integrates a synchronous boost topology for high efficiency in single-output LED driving applications.
• Supports both analog and pulse-width modulation (PWM) dimming control interfaces.

LED Driver IC Applications

• White LED backlighting systems
• Portable electronic display modules

LED Driver IC Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance status according to Monolithic Power Systems documentation. Confirm the QFN package dimensions match the 1.4x1.8mm specification during PCB footprint design. Ensure thermal management strategies account for the specified junction temperature limits under maximum load conditions.

LED Driver IC Selection Notes
