Beschreibung

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 switches 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, 2- wires 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. This IC is available in a small 2.125x1.750mm, 20 balls WLCSP package
