AOZ1073AIL

Overview

The AOZ1073AIL is a synchronous high-efficiency buck regulator from Alpha & Omega Semiconductors, operating within a 4.5V to 16V input voltage range. It delivers up to 3A of continuous output current with an adjustable output voltage down to 0.8V. The device features internal soft start, cycle-by-cycle current limit, and thermal shutdown protection. It operates at a fixed 500kHz PWM frequency and utilizes an SO-8 package rated for ambient temperatures between -40°C and +85°C.

Feature Summary

• Synchronous rectification architecture with integrated high-side and low-side switches
• Integrated protection mechanisms including thermal shutdown, short-circuit protection, and overvoltage protection
• Fixed 500kHz PWM operation with internal soft start capability

Applications

• Point of load DC/DC conversion
• PCIe graphics cards
• Set top boxes
• LCD panels
• Telecom and networking equipment

Procurement Notes

Verify the complete part number against official manufacturer documentation to ensure correct suffix alignment. Confirm that the specific ordering code matches the required package type and temperature rating. Cross-reference datasheet revisions to validate electrical characteristics and pinout configurations before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring a compact solution with integrated synchronous rectification. Ensure the input voltage stays within the specified 4.5V to 16V range. Verify that the required output current does not exceed the 3A continuous limit. Consider the SO-8 package constraints for thermal management in dense PCB layouts.

Part Context

This part belongs to the EZBuck family of simple-to-use buck regulators designed by Alpha & Omega Semiconductors. The series focuses on providing high efficiency and simplified design implementation for various power conversion needs. The AOZ1073AIL specifically targets higher current requirements compared to lower-amperage variants in the same product line.

Replacement Considerations

Consult official manufacturer substitution guides for verified alternatives. Do not assume functional compatibility with other Buck regulators without verifying pinouts, electrical parameters, and control interfaces.
