Overview
The MPQ4425AGQB-AEC1-P is an automotive-grade, high-efficiency synchronous step-down LED driver manufactured by Monolithic Power Systems. It operates with a fixed switching frequency of 2.2 MHz and supports an input voltage range from 4 V to 36 V. The device delivers a continuous output current of 1.5 A and features adjustable output voltage control. Packaged in a QFN-13 form factor, it is designed for robust thermal performance and includes integrated protections against short circuits and over-temperature conditions.
Feature Summary
- Automotive-grade reliability certified under AEC-Q100 standards
- Integrated PWM dimming capability for precise brightness control
- Built-in short circuit and thermal protection mechanisms
Applications
- Automotive interior LED lighting systems
- Vehicle exterior illumination modules
- High-efficiency DC-DC conversion for LED loads
Procurement Notes
Verify the specific suffix -P indicates reel packaging when ordering. Confirm AEC-Q100 qualification aligns with target automotive application requirements. Ensure the QFN-13 package footprint matches the PCB layout design. Cross-reference the datasheet for exact thermal dissipation limits under expected operating conditions.
Selection Notes
Select this component for applications requiring strict automotive qualification and high-frequency operation. The 2.2 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the 1.5 A output current meets the specific LED string requirements without exceeding thermal limits.
Part Context
This part belongs to the MPQ4425 family of synchronous buck LED drivers. It shares core electrical specifications with industrial variants but differs in qualification standards and packaging options. The -AEC1 designation confirms compliance with automotive quality management systems.
Replacement Considerations
MPQ4425AGQB-Z serves as a direct functional substitute with identical electrical characteristics but utilizes tape-and-reel packaging instead of the -P variant.
