Overview
The MPQ4425CGQBE-AEC1-P is a high-efficiency, synchronous step-down LED driver IC from Monolithic Power Systems. It operates with an input voltage range of 4 V to 36 V and delivers a maximum output current of 1.5 A. The device features a fixed switching frequency of 2.2 MHz and supports PWM dimming for brightness control. Packaged in a QFN-13 format, it is qualified under the AEC-Q100 standard for automotive reliability. The component functions as a buck topology converter with adjustable output voltage capabilities.
Feature Summary
- Supports pulse-width modulation (PWM) dimming for precise LED brightness adjustment
- Integrated short circuit and thermal protection mechanisms for enhanced system safety
- Automotive-grade qualification ensuring reliability in demanding environments
Applications
- Automotive interior lighting systems
- Exterior automotive illumination modules
- General-purpose LED lighting drivers requiring high efficiency
Procurement Notes
Verify the specific suffix 'AEC1' confirms automotive grade compliance and 'P' indicates reel packaging. Confirm the wettable flank package variant matches design requirements. Ensure the 2.2 MHz frequency aligns with electromagnetic interference constraints. Validate RoHS compliance status through official documentation before integration.
Selection Notes
Select this component when a compact solution with high switching frequency is required to minimize external passive component size. The 1.5 A current rating suits moderate power LED strings. Consider the QFN-13 package for space-constrained printed circuit board layouts. Verify that the 36 V maximum input voltage covers the system's supply rail variations.
Part Context
This part belongs to the MPQ4425 family of synchronous step-down LED drivers designed for automotive applications. It shares core functionalities with variants like the MPQ4425AGQB but differs in switching frequency and package details. The series targets high-efficiency lighting solutions requiring robust protection features and automotive certification.
Replacement Considerations
The MPQ4425BGQBE-AEC1-Z offers similar functionality but operates at a 400 kHz frequency. The MPQ4425MGQB-AEC1-Z provides comparable performance with a 2.2 MHz frequency. Verify pin compatibility and thermal characteristics when substituting these models.
