Product Details

The MAX77816 evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) for evaluating the IC. The IC 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 highefficiency, 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 five different options such as FPWM mode enable and inductor peak current-limit selection. These options provide design flexibility that allows the IC to cover a wide range of applications and use cases.

The Maxim Command Module (MINIQUSB) can be used to enable USB-to-I²C communication between a Windows®-compatible PC and the EV kit. The EV kit software provides a Windows-based graphical user interface (GUI) to exercise the various features of the IC.
