AOZ1073AIL_8

Overview

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

Feature Summary

Synchronous rectification architecture with low on-resistance switches
Integrated protection mechanisms including thermal shutdown and short-circuit protection
Fixed frequency pulse width modulation for stable regulation

Applications

Point of load DC/DC conversion
PCIe graphics cards
Set top boxes
LCD panels

Procurement Notes

Verify the specific suffix 'AIL_8' against official Alpha & Omega Semiconductor documentation to confirm pinout compatibility and environmental rating variations. Ensure the ordering information matches the exact tape and reel specifications required for your assembly process. Cross-reference the manufacturer's datasheet for any recent lifecycle status updates or recommended alternative components.

Selection Notes

Select this regulator for applications requiring a simple, high-efficiency step-down solution within the 4.5V to 16V input range. The 3A output capability suits moderate power loads where space is constrained by the SO-8 package. Consider the fixed 500kHz switching frequency when designing external passive components to balance size and ripple performance.

Part Context

This component belongs to the EZBuck family of synchronous buck regulators designed for ease of use and high efficiency. It integrates the control logic and power switches into a single small footprint, reducing the bill of materials and board space compared to asynchronous designs. The series targets portable electronics and telecom equipment needing reliable voltage regulation.
