MP4425MGQB-Z

Overview

The MP4425MGQB-Z is a high-efficiency, synchronous step-down LED driver IC from Monolithic Power Systems. It supports an input voltage range of 4 V to 36 V and delivers up to 1.5 A output current. The device operates at a fixed switching frequency of 2.2 MHz and features PWM dimming capability. It includes integrated protection mechanisms such as short circuit and thermal shutdown. The component is housed in a compact 13-QFN (2.5x3) package and is designed for industrial-grade applications with a wide operating temperature range.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's official datasheet to confirm compliance with RoHS standards and lead-free specifications. Ensure that the 13-QFN package dimensions match the target PCB footprint requirements. Confirm that the selected variant meets the required industrial temperature grade specifications for the intended application environment.

Selection Notes

Select this component when a compact solution is required for driving LEDs within a 4 V to 36 V input range. The 2.2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 1.5 A current limit for load requirements and ensure adequate thermal management due to the small QFN package size.

Part Context

This part belongs to the MPQ4425 family of synchronous step-down converters optimized for LED driving. It shares architectural similarities with other MPS LED drivers but is distinguished by its specific 2.2 MHz frequency and 1.5 A current rating. The family targets applications requiring high power density and efficient light regulation.
