AP72250CJ12-7

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 high-efficiency step-up DC-DC conversion. The AP72250 device is easily used by minimizing the external component count due to its adoption of peak current mode control, allowing it to handle wide input-to-output ratios. It also achieves outstanding performance in line and load transient responses and seamless transitions between boost and pass-through modes. The device is available in a small 1.75mm×1.35mm, 12-ball WLCSP.
