AOZ1044PI

Overview

The AOZ1044PI is a synchronous buck switching regulator IC from Alpha & Omega Semiconductor, part of the EZBuck series. It operates with an input voltage range up to 6V and provides a fixed 3.3V output. The device delivers up to 2A of continuous load current. Key electrical parameters include a switching frequency of 1MHz and a quiescent current of 50µA. It features a compact 8-SOIC package with an exposed pad for thermal management.

Feature Summary

Integrated synchronous rectification for high efficiency
Fixed 3.3V output voltage option
Compact surface-mount packaging

Applications

Portable consumer electronics
Battery-powered devices
Embedded systems power supplies

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as per latest datasheet revisions. Check for obsolescence notices or end-of-life announcements prior to procurement. Ensure storage conditions meet moisture sensitivity level requirements.

Selection Notes

Select this component for applications requiring a fixed 3.3V output from low-voltage inputs. Consider the 2A current limit and 1MHz switching frequency for design compatibility. Evaluate thermal performance due to the SOIC-8 package constraints under full load conditions.

Part Context

This part belongs to the EZBuck family of synchronous buck regulators designed for space-constrained applications. It integrates power switches and control logic into a single chip, simplifying board layout compared to discrete solutions.
