Analog Devices / Maxim Integrated MAX77859WEVKIT Evaluation Kit

Analog Devices Inc. MAX77859WEVKIT Evaluation Kit is a fully assembled and tested printed circuit board (PCB) demonstrating the MAX77859. The MAX77859 is a high-efficiency, high-performance buck-boost regulator. It supports USB Type-C™ PPS requirements with programmable output voltage (20mV/step) and programmable output current limit (50mA/step). The IC is capable of 2.5V to 22V input and dynamically adjustable output (through an I2C serial interface) between 3.2V to 16V (internal feedback) or between 3V to 20V (external feedback). The evaluation kit is factory-configured as internal feedback with a default startup output voltage of 5V. Additional startup voltages can be achieved with external feedback resistors.

I/O pins are available to support the I2C serial interface, enable function, forced-PWM mode, and interrupt/power-OK indicator. The I2C target address, feedback configuration, and switching current limit can be adjusted by changing the RSEL resistor (R9). The MAXUSB_INTERFACE allows the use of Windows®-based software with a friendly graphical user interface (GUI) and a detailed register-based interface to exercise all features of the IC. The Analog Devices Inc. MAX77859WEVKIT is compatible with any version of the MAX77859 WLP IC (MAX77859AEWO+T is the default one installed).
