AP61100 Overview
The DIODESTM AP61100/AP61102 is a 1A, synchronous buck converter with a wide input voltage range of 2.3V to 5.5V. The device fully integrates a 110mΩ high-side power MOSFET and an 80mΩ lowside power MOSFET to provide high-efficiency step-down DC-DC conversion. The AP61100/AP61102 device is easily used by minimizing the external ponent count due to its adoption of Constant On-Time (COT) control to achieve fast...
