Detailed Description for MPQ4430GL-AEC1-Z
Product Overview
The MPQ4430GL-AEC1-Z from Monolithic Power Systems Inc. is a surface-mount buck switching regulator for positive, adjustable single-output step-down conversion. It supports input voltages from 3.3 V to 36 V and output voltages from 0.8 V to 36 V, with an output current of 3.5 A. The switching frequency range is 350 kHz to 1.5 MHz, and the device does not use synchronous rectification. It is qualified to AEC-Q100 for automotive use and operates from -40°C to 125°C junction temperature in a 16-PowerVQFN package.
Key Features
- Positive adjustable buck regulator with one output.
- Input voltage range: 3.3 V to 36 V.
- Output voltage range: 0.8 V to 36 V.
- Output current: 3.5 A.
- Switching frequency: 350 kHz to 1.5 MHz.
- Automotive grade, AEC-Q100 qualified, -40°C to 125°C junction temperature range.
- Surface-mount 16-PowerVQFN package, 16-QFN (3x4) device package.
Applications
- Automotive electronic control units requiring a single adjustable positive power rail.
- Logic boards needing adjustable outputs down to 0.8 V.
- Surface-mount step-down conversion from 3.3 V to 36 V inputs in power modules.
Design & Procurement Notes
Designers should confirm that the application needs a single positive adjustable output within the device's input, output, current, and temperature ranges. The absence of synchronous rectification and the 350 kHz to 1.5 MHz switching frequency should be considered during circuit design and thermal management. The AEC-Q100 automotive qualification and 16-PowerVQFN package are relevant for automotive board layout and junction temperature control.
