0.6V TO 5.5V INPUT SYNCHRONOUS BOOST CONVERTER WITH 4.7A SWITCHES

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 high-

efficiency step-up DC-DC conversion.

MODE

VIN

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 x 1.35mm, 12-ball WLCSP.
