AP72202

Description

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 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 AP72202 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 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.
