MPQ4425AGQB-Z

Overview

The MPQ4425AGQB-Z is a high-efficiency, synchronous step-down LED driver IC from Monolithic Power Systems. It features a wide input voltage range of 4 V to 36 V and delivers up to 1.5 A output current. Operating at a fixed frequency of 2.2 MHz, the device utilizes a buck topology within a compact QFN-13 package. Designed for industrial applications, it supports PWM dimming and includes integrated short circuit and thermal protection mechanisms.

Feature Summary

Synchronous buck topology for high efficiency
Integrated PWM dimming control capability
Built-in short circuit and thermal protection

Applications

Industrial LED lighting systems
General illumination drivers
High-power LED arrays

Procurement Notes

Verify the specific suffix 'Z' indicates the industrial grade variant distinct from automotive qualified versions. Confirm package integrity upon receipt as components are supplied in reel packaging. Ensure design compatibility with the specified 4 V to 36 V input range before integration into final assemblies.

Selection Notes

Select this component for applications requiring a single-channel, high-current LED drive solution. The 2.2 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the QFN-13 footprint for space-constrained PCB layouts requiring surface-mount installation.

Part Context

This part belongs to the MPQ4425 series of LED drivers manufactured by Monolithic Power Systems. The series offers various grades, including automotive and industrial options. The AGQB-Z designation specifically identifies the industrial-grade version with a QFN-13 package, differing from automotive variants which may carry additional qualification suffixes.

Replacement Considerations

The MPQ4425AGQB-AEC1-Z serves as an automotive-grade alternative within the same family. Verify that the application environment meets industrial rather than automotive qualification requirements when substituting between these specific suffixes.
