AOZ1606DI

Overview

The AOZ1606DI is a synchronous buck regulator from the EZBuck series by Alpha & Omega Semiconductor. It integrates high-side and low-side power switches to deliver up to 500 mA output current with a switching frequency of 3 MHz. The device supports an input voltage range of 2.7 V to 5.5 V and features an adjustable output voltage. Packaged in an 8-DFN (4x5 mm) configuration, it offers compact integration for space-constrained designs.

Feature Summary

• Integrates synchronous rectification within a single package
• Supports high-frequency operation for reduced passive component size
• Includes internal compensation for simplified design

Applications

• Portable consumer electronics
• Battery-powered devices
• Embedded systems requiring efficient step-down conversion

Procurement Notes

Verify the specific suffix 'DI' against the manufacturer datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with the required output voltage setting via external resistors. Confirm RoHS compliance status for your region before finalizing procurement.

Selection Notes

Select this component when a compact solution is needed for low-current applications. The 3 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the load current does not exceed the 500 mA limit and that the input voltage remains within the specified operating range.

Part Context

This part belongs to the EZBuck family, designed for simple, cost-effective power management. It combines control logic with power MOSFETs to minimize board space. The DFN package facilitates surface-mount assembly in dense layouts typical of modern portable electronics.

Replacement Considerations

Check for direct pin-compatible substitutes within the same EZBuck family or similar 500 mA regulators. Verify that alternative parts match the 3 MHz switching frequency and input voltage range to ensure circuit stability without redesign.
