Overview
The MPQ3367GF-AEC1-P is a six-channel boost WLED driver IC designed for LCD panel backlighting. It operates from a 3.5V to 36V input supply and delivers up to 150mA per channel with a maximum output voltage of 50V. The device supports switching frequencies between 400kHz and 2.2MHz. It features I2C control, analog/PWM dimming with a 15000:1 ratio, and AEC-Q100 automotive qualification. Packaged in a QFN-24, it functions within a -40°C to +125°C temperature range.
Feature Summary
- Six independent current source channels for precise LED string regulation
- I2C digital interface for configuration and control
- Supports analog, PWM, and hybrid dimming modes
- Integrated protection against overcurrent, overvoltage, and thermal faults
Applications
- Automotive display backlighting systems
- Small to medium LCD panel backlights
- Tablet and notebook computer displays
Procurement Notes
Verify the specific suffix GF against official Monolithic Power Systems documentation to confirm pinout and electrical characteristics. Ensure the component meets AEC-Q100 requirements for your target automotive application. Cross-reference the datasheet for exact thermal performance and recommended external component values.
Selection Notes
Select this driver for applications requiring high channel count and wide dimming ratios. The integrated boost converter simplifies design by eliminating external power switches. Consider the QFN-24 package for space-constrained PCB layouts. Verify compatibility with system I2C bus speeds and PWM input frequencies.
Part Context
This part belongs to the MPQ3367 family of automotive-grade LED drivers. It shares core functionality with variants like MPQ3367AGR-AEC1-P but may differ in packaging or specific manufacturing lot attributes. The MPQ series denotes industrial/automotive grade components from Monolithic Power Systems.
