Datasheet Summary
HIGH EFFICIENCY SYNCHRONOUS DC-DC BUCK-BOOST CONVERTER WITH 4.3A SWITCHES
Description
The AP72200 is a high-current synchronous buck-boost converter providing high efficiency, excellent transient response, and high DC output accuracy. The targeted applications are smartphones, tablets, and other handheld devices. The AP72200 utilizes a four-switch Hbridge configuration to support buck and boost operation. The buckboost provides at least 2A output current.
Pin Assignments
The current control scheme handles wide input/output voltage ratios and provides low external ponent count with outstanding performance in line/load transient response and seamless transition between buck and...
