RoHS: Unknown
View Datasheet Manufacturer Site View Pricing & Stock

The MAX77816 is a high-current, high-efficiency buck-boost regulator targeting single-cell Li-ion battery-powered applications. It supports a wide output voltage range from 2.60V to 5.14V. The IC allows 5A (TYP) maximum switch current. In buck mode, the output current can go as high as 4A, and in boost mode, the maximum output current can be 3A. A unique control algorithm allows high efficiency, outstanding line/load transient response, and seamless transition between buck and boost modes. The IC features I2C-compatible serial interface. The I2C interface allows the output voltage to be dynamically adjusted thus enabling finer control of system power consumption. The I2C interface also provides features such as enable control and device status monitoring. The multifunction GPIO pin is register settable to 5 different options such as FPWM mode enable and inductor peak current level selection. These options provide design flexibility that allows the IC to cover a wide range of applications and use cases. Design Solution: Boost the Run-Time of Portable Electronics with a One-Two Punch ›
