Overview
The MPQ4425MGQB-AEC1-P is a 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 utilizes a fixed switching frequency of 2.2 MHz and features PWM dimming capabilities. It is housed in a QFN-13 package and supports surface mount installation. The component is qualified under the AEC-Q100 standard for automotive applications, ensuring reliability within an operating temperature range of -40°C to +125°C.
Feature Summary
- Supports pulse-width modulation (PWM) dimming for precise light control
- Includes integrated short circuit and thermal protection mechanisms
- Features high-efficiency synchronous buck topology for optimized power conversion
Applications
- Automotive interior lighting systems
- Vehicle exterior illumination circuits
- General-purpose LED lighting drivers requiring AEC-Q100 compliance
Procurement Notes
Verify the specific suffix 'P' indicates the tape-and-reel packaging configuration distinct from other variants. Confirm that the AEC-Q100 qualification aligns with target automotive grade requirements. Ensure the QFN-13 footprint matches the printed circuit board layout specifications. Cross-reference the datasheet for any updates regarding lead-free status or material declarations.
Selection Notes
Select this component when designing automotive LED drivers requiring a 1.5 A continuous output capability. The 2.2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. The wide 4 V to 36 V input range accommodates various vehicle electrical architectures. Consider the thermal performance characteristics inherent to the QFN-13 package for heat dissipation planning.
Part Context
This part belongs to the MPQ4425M series of high-efficiency synchronous step-down LED drivers. The series includes variants with different packaging options and pin configurations, such as wettable flank packages. The MPQ4425MGQB-AEC1-P specifically denotes the automotive-grade version with standard QFN-13 packaging and reel distribution.
Replacement Considerations
Direct substitutes include MPQ4425MGQB-AEC1-Z and MPQ4425AGQBE-AEC1-Z. Verify package compatibility and pinout alignment before substitution. Ensure the alternative variant maintains the required AEC-Q100 qualification and 1.5 A output current rating.
