Overview
The MPQ4425BGQB-AEC1-Z is an automotive-grade, high-efficiency synchronous step-down LED driver manufactured by Monolithic Power Systems. It features a buck topology with a single output capable of delivering 1.5 A. The device operates within an input voltage range of 4 V to 36 V and supports a fixed switching frequency of 400 kHz. Packaged in a QFN-13 form factor for surface mount installation, it is qualified under the AEC-Q100 standard. The IC includes PWM dimming capabilities and functions as an open-drain output driver.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q100 standards
- Integrated PWM dimming functionality for precise control
- High-efficiency synchronous buck converter topology
Applications
- Automotive LED lighting systems
- General-purpose LED illumination drivers
Procurement Notes
Verify the specific suffix Z against official manufacturer documentation to confirm reel packaging specifications. Ensure the selected variant matches the required 400 kHz switching frequency, as other family members may operate at different frequencies. Confirm that the QFN-13 package aligns with the target PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when a fixed 400 kHz switching frequency is required for EMI management or filter size optimization. The 1.5 A current rating suits moderate-power LED loads. Verify compatibility with the system's input voltage range of 4 V to 36 V. Consider the QFN-13 package thermal performance relative to the expected power dissipation of 2.08 W in the final application design.
Part Context
This part belongs to the MPQ4425 series of synchronous step-down LED drivers from Monolithic Power Systems. The series offers various switching frequencies and package options to suit different automotive and industrial applications. The BGQB variant specifically denotes the 400 kHz frequency option within this product line.
Replacement Considerations
MPQ4425AGQB-AEC1-P: Offers identical electrical parameters except for a 2.2 MHz switching frequency. MPQ4425MGQB-AEC1-P: Similar specifications with a 2.2 MHz switching frequency.
