MAX77859WEVKIT#

MAX77859WEVKIT# is an evaluation kit for MAX77859. It is a fully assembled and tested printed circuit board (PCB) that demonstrates the MAX77859, a high-efficiency, high-performance buck-boost regulator with a peak switching current of 7.8A. 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 I2C serial interface) between 3.2V to 16V (internal feedback) or between 3V to 20V (external feedback). The EV kit is factory-configured as internal feedback with a default startup output voltage of 5V. Other 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, switching current limit, and feedback configuration can be adjusted by changing the RSEL resistor (R9).
