AOZ1270AQI

Overview

The AOZ1270AQI is a synchronous step-down DC-DC converter manufactured by Alpha & Omega Semiconductor Inc. It operates with an input voltage range of 4.5V to 36V and delivers a maximum output current of 3A. The device features adjustable output voltage from 0.8V to 22.95V and utilizes a fixed switching frequency of 370kHz. Packaged in a thermally enhanced 8-DFN (4x5mm) footprint, it supports operation across a temperature range of -40°C to 85°C.

Feature Summary

Integrates high-side and low-side power FETs for simplified design
Supports PWM dimming control for LED applications
Includes internal soft-start and protection circuits

Applications

LED lighting drivers
General-purpose point-of-load regulation
Industrial control systems

Procurement Notes

Verify the specific suffix 'AQI' against official datasheets to confirm package type and thermal characteristics. Ensure compatibility with required input/output voltage ranges before integration. Confirm RoHS compliance status through manufacturer documentation.

Selection Notes

Select this component when a compact solution is required for 3A loads within a 36V input limit. The integrated FETs reduce external component count compared to non-integrated alternatives. Consider the 370kHz frequency for balancing efficiency and passive size requirements.

Part Context

This part belongs to the EZBuck™ family of synchronous buck regulators. These devices are designed to simplify power supply design by integrating the controller and power switches. The family targets applications requiring high efficiency and small form factors.
