AP62150 Overview
The AP62150 is a 1.5A, synchronous buck converter with a wide input voltage range of 4.2V to 18V. The device fully integrates a 90mΩ highside power MOSFET and a 65mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. Pin Assignments (Top View) The AP62150 device is easily used by minimizing the external ponent count due to its adoption of Constant On-Time (COT) control to achieve fast...
