Overview
The AOZ1268AQI is a high-efficiency synchronous buck regulator IC from Alpha & Omega Semiconductor. It operates with an input voltage range of 6.5V to 28V and delivers up to 10A of continuous output current. The device features an adjustable output voltage starting from 0.6V, housed in a compact 22-PowerVFQFN package. Designed for easy implementation, it integrates internal power switches and control logic to simplify DC/DC conversion applications.
Feature Summary
- Integrates synchronous rectification for improved efficiency
- Supports adjustable output voltage regulation
- Operates within a wide input voltage range
Applications
- Point-of-load voltage regulation
- Industrial equipment power supplies
- Communication infrastructure systems
Procurement Notes
Verify the specific suffix 'QI' against official Alpha & Omega documentation to confirm RoHS compliance and lead-free status. Ensure the 22-PowerVFQFN package dimensions match your PCB footprint requirements. Confirm availability status as components may be subject to obsolescence or supply chain constraints.
Selection Notes
Select this component when a single-phase, high-current buck solution is required within a 28V input limit. The integrated design reduces external component count compared to discrete solutions. Verify thermal management capabilities for the target 10A load within the specified QFN package constraints.
Part Context
This part belongs to the EZBuck family of regulators, designed for simplified power management. It serves as a monolithic solution for stepping down higher bus voltages to lower logic or peripheral levels. The integration of drivers and MOSFETs distinguishes it from controller-only alternatives.
Replacement Considerations
Consult official manufacturer substitution guides for direct pin-compatible alternatives. Generic equivalents may lack the specific integrated protection features or efficiency characteristics of the original design.
