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.
