AOZ2263AQI-15

Voltage Regulators - DC DC Switching Regulators Overview

The AOZ2263AQI-15 is a synchronous buck switching regulator IC from the EZBuck series by Alpha & Omega Semiconductor. It operates with an input voltage range of 4V to 28V and provides a single adjustable output between 0.8V and 23.8V. The device delivers up to 12A of continuous output current at a fixed switching frequency of 1MHz. It utilizes a 22-PowerVFQFN package (22-QFN, 4x4mm) for surface mount installation. The component supports positive output configuration and functions within an ambient temperature range of -40°C to 85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '15' corresponds to the required pinout or thermal pad configuration as defined in the official datasheet. Confirm RoHS3 compliance status if environmental regulations apply to your assembly process. Ensure the 22-QFN package dimensions match your PCB land pattern design guidelines before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a 12A current capacity is required within a 4V to 28V input window. The 1MHz frequency is suitable for designs prioritizing component size over extreme light-load efficiency. Compare against the AOZ2261 series if lower 8A current ratings are sufficient for the application, or consider other EZBuck variants for different package constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the AOZ2263 family of high-efficiency synchronous regulators. It shares core topology with siblings like the AOZ2263AQI-10 but differs in internal resistance characteristics associated with the specific suffix designation. The series is designed to replace older discrete solutions in space-constrained power management applications.
