The MAX77813 is a high-efficiency step-up/step-down(buck-boost) converter targeted for single-cell Li+/Li-ionbattery powered applications. The device maintains aregulated output voltage from 2.6V to 5.14V across aninput voltage range of 2.3V to 5.5V. The device supportsup to 2A of output current in boost mode and up to 3A inbuck mode.The device seamlessly transitions between buck andboost modes. A unique control algorithm allows high-efficiency,outstanding load, and line transient response.Dedicated enable and power-OK pins allow simple hardwarecontrol. An I2C serial interface is optionally used fordynamic voltage scaling, system power optimization, andfault read-back. The device supports two inductor currentlimit options selected by the ILIM pin.The MAX77813 is available in a 20-bump, 1.83mm x2.13mm wafer-level package (WLP).ApplicationsSingle-Cell Li-ion Powered ApplicationsHandheld Scanners, Mobile Payment Terminals, Security CamerasAR/VR Headsets
