Overview

The MAX77813 is a high-efficiency step-up/step-down (buck-boost) converter targeted for single-cell Li+/Li-ion battery powered applications. The device maintains a regulated output voltage from 2.6V to 5.14V 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, 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 device supports two inductor switching current limit options selected by the ILIM pin. The MAX77813 is available in a 20-bump, 2.13mm x 1.83mm wafer-level package (WLP).
