AOZ1073AIL-4

Overview

The AOZ1073AIL-4 is a synchronous high-efficiency buck regulator from Alpha & Omega Semiconductor. It operates within a 4.5V to 16V input voltage range and delivers up to 3A of continuous output current. The device features an adjustable output voltage down to 0.8V and utilizes internal switches with 85mΩ high-side and 30mΩ low-side resistance. It includes fixed 500kHz PWM operation, cycle-by-cycle current limit, thermal shutdown, and overvoltage protection. 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 for enhanced efficiency
Integrated protection mechanisms including thermal shutdown and short-circuit protection
Adjustable output voltage capability down to 0.8V
Fixed 500kHz switching frequency for stable power conversion

Applications

Point of load DC/DC conversion
Telecom and networking datacom equipment
Set top boxes and DVD drives
LCD panels and cable modems

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical tolerances. Ensure that any replacement components match the original SO-8 package dimensions and thermal characteristics. Confirm RoHS compliance status through current datasheets before integration into production designs.

Selection Notes

Select this regulator for applications requiring efficient step-down conversion from 4.5V to 16V inputs. The 3A output capacity suits moderate power loads in portable or space-constrained electronics. Consider the integrated protections for robust system reliability without external circuitry complexity.

Part Context

This component belongs to the EZBuck series of simple-to-use synchronous buck regulators. The series is designed for high efficiency and minimal external component count. The AOZ1073 variant specifically targets applications needing reliable 3A current delivery in a small form factor.
