MP4425AGQB-Z

Overview

The MP4425AGQB-Z is a high-efficiency synchronous step-down LED driver IC manufactured by Monolithic Power Systems. It features a buck topology with a single output channel capable of delivering up to 1.5 A of continuous output current. The device operates within an input voltage range of 4 V to 36 V and supports a fixed switching frequency of 2.2 MHz. It utilizes a QFN-13 package and supports PWM dimming for brightness control. The component is rated for operation between -40°C and +125°C, ensuring reliability in demanding environments.

Feature Summary

Synchronous buck topology for high conversion efficiency
Integrated 1.5 A power switch for compact design
Fixed 2.2 MHz switching frequency reduces external component size
PWM dimming interface for precise brightness adjustment

Applications

LED lighting systems
General-purpose DC-DC conversion
Battery-powered devices requiring efficient voltage regulation

Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with your design requirements. Confirm RoHS compliance status and check for any automotive or industrial grade distinctions if applicable. Ensure that the ordering information matches the exact part number including all trailing characters to avoid receiving incorrect revisions or packages.

Selection Notes

Select this component when a compact, high-frequency solution is needed for driving LEDs from a wide input voltage range. The 2.2 MHz frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Consider the thermal performance of the QFN-13 package and ensure adequate PCB copper area for heat dissipation given the 1.5 A output capability.

Part Context

This part belongs to the MPS LED driver family, designed specifically for applications requiring efficient current regulation. It integrates the control logic and power switches into a single small footprint, simplifying the bill of materials and reducing board space. The synchronous design improves efficiency over traditional diode-based rectification, particularly at higher load currents.
