Description
General part information
MAX77801 Series
The MAX77801 is a high-efficiency, step-up/step-down (buck-boost) converter targeted for single-cell, Li-ion battery-powered applications. The device maintains a regulated output voltage from 2.6V to 4.18V across an input voltage range of 2.3V to 5.5V. The device supports up to 2A of output current in boost mode and up to 3A in buck mode.The device seamlessly transitions between buck and boost modes. A unique control algorithm allows high-efficiency and outstanding load and line-transient response.Dedicated enable and power-OK pins allow simple hardware control. An I2C serial interface is optionally used for dynamic voltage scaling, system power optimization, and fault read-back.The MAX77801 is available in a 20-bump, 2.13mm x 1.83mm 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
