AP72200

HIGH EFFICIENCY SYNCHRONOUS DC-DC BUCK-BOOST CONVERTER WITH 4.3A SWITCHES

Description

Pin Assignments

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 H-

bridge configuration to support buck and boost operation. The buck-

boost provides at least 2A output current.

The current control scheme handles wide input/output voltage ratios

and provides low external component count with outstanding

performance in line/load transient response and seamless transition

between buck and boost modes.

The AP72200 features I²C compatible, two-wire serial interface

consisting of a bidirectional serial-data line, SDA, and a serial-clock

line, SCL. It supports SCL clock rates up to 3.4MHz.

The AP72200 also features UVLO, OTP, and OCP to protect the

circuit.
