AOZ1073AIL General Description

The AOZ1073AIL is an innovative synchronous buck converter IC developed by Alpha and Omega Semiconductor (AOS) to provide a high-performance solution for various applications. With an input voltage range from 4.5V to 18V and an adjustable output voltage from 0.8V to 6V, this IC is well-suited for use in portable devices and industrial equipment. Its integration of high-efficiency power MOSFETs and peak current mode control scheme ensures stable and reliable performance, while the fixed switching frequency of 1.5MHz enables compact designs and minimizes the need for external components. The AOZ1073AIL also incorporates comprehensive protection features such as overcurrent protection (OCP), overvoltage protection (OVP), and thermal shutdown to ensure system safety under fault conditions. Furthermore, its small footprint and low-profile package enhance thermal performance and facilitate integration into space-constrained applications
