AP72250 Description
Pin Assignments The AP72250 is a synchronous boost converter with a minimum 1V input startup voltage and can operate in a wide input voltage range of 0.6V to 5.5V. The device fully integrates a 20mΩ high-side power MOSFET and a 26mΩ low-side power MOSFET to provide highefficiency step-up DC-DC conversion. The AP72250 device is easily used by minimizing the external ponent count due to its adoption of peak current...
