AOZ1050PI

Overview

The AOZ1050PI is a high-efficiency, easy-to-use 2 A synchronous buck regulator from Alpha & Omega Semiconductor. It operates within an input voltage range of 4.5 V to 18 V and provides up to 2 A of continuous output current with an adjustable output voltage down to 0.8 V. The device features internal high-side and low-side switches, cycle-by-cycle current limit, pre-bias start-up, short-circuit protection, and thermal shutdown.

Feature Summary

• Synchronous Buck architecture with integrated high-side and low-side switches
• Adjustable output voltage capability down to 0.8 V
• Comprehensive protection including thermal shutdown and short-circuit protection

Applications

• Point of load DC/DC converters
• LCD TV power supplies
• Set top boxes
• DVD and Blu-ray players/recorders
• Cable modems

Procurement Notes

Verify the specific suffix 'PI' corresponds to the SO-8 package variant when sourcing. Confirm RoHS compliance status for the specific manufacturing batch. Check for any product change notices (PCN) regarding pinout or electrical parameter updates before finalizing design-in.

Selection Notes

Select this component for applications requiring a compact synchronous buck solution with 2 A output capacity. Ensure the input voltage stays within the 4.5 V to 18 V range. Consider the SO-8 exposed pad package for thermal management requirements in point-of-load designs.

Part Context

The AOZ1050PI belongs to the EZBuck family of synchronous buck regulators. It is part of a series that includes variants with different current ratings, such as the 3 A AOZ1051PI and 4 A AOZ1052PI, offering scalable solutions for various power density needs.

Replacement Considerations

Direct functional substitutes within the same family include the AOZ1051PI (3 A) and AOZ1052PI (4 A), provided the higher current ratings are acceptable. Verify package compatibility and thermal performance when substituting with higher-rated devices.
