Overview
The AOZ1267QI-02 is a synchronous step-down DC-DC regulator from the EZBuck series, manufactured by Alpha & Omega Semiconductor. It integrates high-side and low-side power MOSFETs to deliver an output current of 8A. The device operates with an input voltage range up to 24V and supports adjustable output voltages. Designed for surface-mount installation in compact packages, it features integrated control logic for efficient power conversion in space-constrained applications.
Feature Summary
- Integrates synchronous rectification for improved efficiency
- Includes internal bootstrap diode and gate drivers
- Features fixed-frequency PWM operation
- Incorporates thermal shutdown and overcurrent protection
Applications
- Point-of-load regulation for industrial equipment
- Power supply stages for consumer electronics
- Battery-powered devices requiring efficient voltage stepping
- Communication infrastructure power distribution
Procurement Notes
Verify component authenticity through authorized Alpha & Omega Semiconductor distributors. Confirm package integrity and pin alignment against datasheet specifications before integration. Ensure storage conditions comply with moisture sensitivity level requirements to prevent soldering defects during assembly processes.
Selection Notes
Select this regulator when an 8A continuous output current is required within a 24V input limit. Evaluate thermal performance based on expected ambient temperatures and PCB copper area availability. Compare footprint dimensions against available board space to ensure compatibility with existing mechanical constraints and assembly tools.
Part Context
This component belongs to the EZBuck family of synchronous buck regulators designed by Alpha & Omega Semiconductor. The series targets applications demanding high power density and simplified design cycles. The AOZ1267QI-02 variant specifically addresses needs for moderate current loads with fixed switching frequency characteristics typical of this product line.
Replacement Considerations
Check for direct pin-compatible alternatives within the same EZBuck series if supply constraints exist. Verify that substitute components match the 8A current rating and 24V maximum input voltage specifications to maintain system performance without redesign.
