Overview
The AOZ1072AI is a synchronous buck switching regulator manufactured by Alpha & Omega Semiconductor Inc. It integrates high-side and low-side N-channel power MOSFETs into an 8-SOIC package. The device supports adjustable output voltages with a maximum output current of 5A. It operates from an input voltage range of 4.5V to 28V. Key features include fixed frequency operation, soft-start capability, and comprehensive protection mechanisms such as over-current, over-temperature, and undervoltage lockout.
Feature Summary
- Integrates synchronous rectification with internal high-side and low-side N-channel MOSFETs for efficient power conversion.
- Provides adjustable output voltage control via external resistor network.
- Includes built-in protection against over-current, over-temperature, and input undervoltage conditions.
Applications
- Point-of-load regulation in industrial equipment
- Power distribution systems for embedded controllers
- Battery-powered devices requiring efficient step-down conversion
Procurement Notes
Verify the exact suffix and revision level when ordering, as Alpha & Omega Semiconductor may update pinouts or electrical characteristics across revisions. Confirm RoHS compliance status and packaging type (tube vs. tape) directly with the manufacturer or authorized distributor. Check for any recent Product Change Notices (PCN) that might affect form, fit, or function before finalizing procurement plans.
Selection Notes
Select this component for applications requiring a compact solution with integrated power switches. Ensure the input voltage does not exceed the 28V absolute maximum rating. Verify that the required output current stays within the 5A limit under all operating temperature conditions. Consider thermal management requirements due to the small 8-SOIC package size and potential power dissipation during high-load operations.
Part Context
This part belongs to the AOZ10xx series of synchronous buck regulators from Alpha & Omega Semiconductor. These regulators are designed for space-constrained applications where efficiency and integration are critical. The series typically offers fixed frequencies and various output configurations, catering to general-purpose DC-DC conversion needs in consumer and industrial electronics.
Replacement Considerations
Direct replacements must match the 8-SOIC package, 5A current capability, and 4.5V-28V input range. Verify pin compatibility and control interface similarities. Consult manufacturer cross-reference lists for verified substitutes like the AOZ1073AI if different output configurations are acceptable.
