AOZ1056AIL

Overview

The AOZ1056AIL is a discontinued synchronous buck switching regulator IC from Alpha & Omega Semiconductor Inc., part of the EZBuck series. It features an adjustable output voltage range from 0.8V to 16V with a maximum continuous output current of 2A. The device operates with an input voltage range of 4.5V to 16V and utilizes a fixed switching frequency of 340kHz. Packaged in an 8-SOIC surface-mount format, it supports positive output configuration.

Applications

• Point-of-load regulation for embedded systems
• Battery-powered portable devices requiring efficient step-down conversion
• Industrial control circuits needing stable low-voltage power rails

Procurement Notes

Verify component authenticity through authorized channels as this part is officially obsolete. Confirm that the 8-SOIC package dimensions match your PCB footprint requirements. Ensure design compatibility with the 340kHz switching frequency regarding external inductor and capacitor selection. Check for RoHS3 compliance documentation if required by specific regulatory standards.

Selection Notes

Select this component only if the 2A current capacity and 16V maximum input voltage align with system demands. Consider the fixed 340kHz frequency for EMI management and passive component sizing. Evaluate thermal performance within the -40°C to 85°C operating range. Since the part is discontinued, assess long-term supply chain stability before finalizing the design.

Part Context

The AOZ1056AIL belongs to the EZBuck family of non-synchronous buck regulators designed for cost-sensitive applications. It integrates high-side and low-side MOSFETs to minimize external component count. The 8-SOIC package provides a compact solution for space-constrained designs requiring reliable DC-DC conversion without complex control loops.

Replacement Considerations

AOZ1056AI is listed as a parameter-equivalent alternative. ADP2302ARDZ-R7 from Analog Devices Inc. is available as a similar functional replacement.
