AP62250 Overview
The AP62250 is a 2.5A, synchronous buck converter with a wide input voltage range of 4.2V to 18V. The device fully integrates a 75mΩ highside power MOSFET and a 45mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. Pin Assignments (Top View) The AP62250 device is easily used by minimizing the external ponent count due to its adoption of Constant On-Time (COT) control to achieve fast...
