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 Hbridge configuration to support buck and boost operation. The buckboost 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.
2 The AP72200 features I C 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. TOP VIEW
