AOZ1017AIL

Overview

The AOZ1017AIL is a synchronous buck converter from the EZBuck series by Alpha & Omega Semiconductor. It operates with an input voltage range of 4.5V to 16V and provides an adjustable output voltage between 0.8V and 16V. The device delivers a maximum output current of 3A at a fixed switching frequency of 500kHz. Designed for surface-mount applications, it functions within an ambient temperature range of -40°C to 85°C.

Feature Summary

• Integrated synchronous rectification architecture eliminates external Schottky diodes to improve efficiency and reduce component count.
• Fixed 500kHz switching frequency enables the use of compact passive components while maintaining stable regulation under varying load conditions.

Applications

• Portable consumer electronics requiring efficient step-down power conversion
• Battery-powered devices utilizing single-cell lithium-ion or lithium-polymer sources
• Embedded systems needing regulated low-voltage rails for logic or peripheral circuits

Procurement Notes

Verify the specific suffix 'AIL' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure design compatibility with the 500kHz switching frequency and thermal requirements for the intended operating environment. Confirm RoHS compliance status directly with the supplier documentation prior to integration.

Selection Notes

Select this component when a compact, non-synchronous-free solution is required for inputs up to 16V. Evaluate thermal performance based on the 3A continuous current capability and the specified junction-to-ambient characteristics. Compare against alternative EZBuck variants if different switching frequencies or higher current ratings are necessary for the target application.

Part Context

This part belongs to the EZBuck family of DC-DC converters, designed for high-efficiency power management in space-constrained environments.
