Overview
The AOZ2140DI is a dual-output buck switching regulator IC from Alpha & Omega Semiconductor, utilizing EZBUCK architecture with constant on-time control. It integrates two independent regulators capable of delivering up to 3A and 5A respectively. The device features an adjustable output voltage range starting from 0.8V. Packaged in a 14-WFDFN exposed pad format, it supports compact power designs for portable electronics.
Feature Summary
- Dual independent output channels for flexible power distribution
- EZBUCK constant on-time control architecture for stable operation
- Integrated power switches eliminating external inductor requirements
Applications
- Portable consumer electronics power management
- Battery-powered devices requiring multiple voltage rails
- Embedded systems with space-constrained layouts
Procurement Notes
Verify the specific suffix 'DI' against official Alpha & Omega Semiconductor documentation to confirm package type and temperature grade. Ensure compatibility with system input voltage ranges and thermal dissipation requirements before integration. Cross-reference datasheet revisions for any design changes.
Selection Notes
Select this component when dual isolated or non-isolated outputs are required from a single input source. Evaluate the combined current capability against peak load demands. Consider the thermal performance of the exposed pad package for high-density PCB implementations.
Part Context
This part belongs to the AOZ21xx series of EZBUCK regulators designed for low-component-count solutions. It represents Alpha & Omega's approach to integrating power stages into small footprints, targeting applications where board space is limited but multiple regulated voltages are necessary.
Replacement Considerations
Check for direct pin-compatible alternatives within the same manufacturer portfolio that offer similar current ratings. Verify if other series members provide enhanced efficiency or different package options suitable for the specific application constraints.
