AOZ1615DI

Overview

The AOZ1615DI is a synchronous buck switching regulator IC manufactured by Alpha & Omega Semiconductor Inc. It features an adjustable output voltage range starting from 0.6V with a single output channel capable of delivering up to 1.5A. The device operates within an input voltage range of 4.5V to 5.5V and utilizes a fixed 3MHz switching frequency for efficient power conversion. Packaged in an 8-WFDFN exposed pad configuration, it integrates internal power switches for high efficiency. The component supports positive adjustable regulation and includes protection features such as UVLO.

Feature Summary

Synchronous rectification architecture for enhanced efficiency
Fixed 3MHz switching frequency enabling compact passive component selection
Integrated bootstrap diode and driver circuitry
Adjustable output voltage capability down to 0.6V

Applications

Point-of-load (POL) voltage regulation
Battery-powered portable devices
Embedded systems power distribution

Procurement Notes

Verify the specific suffix 'DI' against the manufacturer's current datasheet to confirm pinout compatibility and thermal specifications. Ensure the ordering documentation explicitly references the 8-WFDFN package variant. Cross-reference the RoHS compliance status with the latest environmental declarations prior to final procurement authorization.

Selection Notes

Select this component when designing low-voltage, high-current DC-DC conversion stages requiring small footprint solutions. The 3MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the load current requirements do not exceed the 1.5A continuous limit under maximum operating temperature conditions.

Part Context

This part belongs to the AOZ16xx series of synchronous buck regulators from Alpha & Omega Semiconductor. The series focuses on providing integrated power management solutions for space-constrained applications. The AOZ1615DI specifically targets inputs around 5V, making it suitable for USB-powered or battery-backed logic supply rails.
