AP72200

AP72200 HIGH EFFICIENCY SYNCHRONOUS DC-DC BUCK-BOOST CONVERTER WITH 4.3A SWITCHES Description 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. Pin Assignments 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. This IC is available in a smal...
