Analog Devices Inc.

The MAX77801 is a high-efficiency, step-up/step-down(buck-boost) converter targeted for single-cell, Li-ionbattery-powered applications. The device maintains aregulated output voltage from 2.6V to 4.18V 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-efficiencyand 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 MAX77801 is available in a 20-bump, 1.83mm x2.13mm wafer-level package (WLP) and also 20-pin,4mm x 4mm TQFN.ApplicationsAR/VR HeadsetsHandheld Scanners, Mobile Payment Terminals, Security CamerasSingle-Cell, Li-Ion Battery-Powered Devices
