MPQ7221GRE-AEC1-Z

Overview

The MPQ7221GRE-AEC1-Z is a single-channel LED driver IC from Monolithic Power Systems, designed for automotive applications with AEC-Q100 qualification. It operates as a synchronous buck converter with an input voltage range of 4.5 V to 16 V and delivers up to 80 mA output current. The device features a fixed switching frequency of 1.2 MHz and supports PWM dimming. It is housed in a QFN-24 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Single-channel synchronous buck topology for efficient LED driving
• Integrated PWM dimming control interface
• Automotive-grade reliability certified under AEC-Q100 standards

Applications

• Automotive tail lamp illumination systems
• LED lighting driver circuits in vehicle exteriors
• High-reliability automotive LED modules

Procurement Notes

Verify the complete part number including suffixes such as -Z or -P against official MPS documentation to ensure correct packaging and specifications. Confirm AEC-Q100 compliance requirements match your specific automotive application standards before procurement.

Selection Notes

Select this component for applications requiring a single high-current LED channel with integrated buck conversion. Ensure the input voltage stays within the 4.5 V to 16 V range and that thermal management accommodates the specified power dissipation limits in the QFN-24 package.

Part Context

This part belongs to the MPQ7221 series of automotive LED drivers. It shares the family's focus on robust performance in harsh environments but differs from multi-channel variants like the MPQ3326 by providing only one regulated output channel for simpler lighting designs.
