AOZ1240AI

Overview

The AOZ1240AI is a single-output, adjustable step-down switching regulator from the EZBuck series by Alpha & Omega Semiconductor. It delivers up to 2A of continuous output current with an input voltage range of 4.5V to 32V and an adjustable output voltage starting at 0.8V. Operating at a fixed switching frequency of 370kHz, it integrates internal power switches for high efficiency in compact designs. The device is housed in an 8-SOIC package and supports surface-mount installation.
