The AP72202 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 AP72202 utilizes a four-switch Hbridge configuration to support buck and boost operation. The buckboost provides at least 2A out.
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 AP72202 also features UVLO, OTP, and OCP to protect the circuit.
This IC is available in a small 2.125 × 1.750mm, 20 balls WLCSP package.
