MAX77859WEVKIT

Product Details

The MAX77859 evaluation kit (EV kit) 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 R_SEL resistor (R9). MAXUSB_INTERFACE# allows the use of Windows^®-based software with a friendly graphical user interface (GUI) as well as a detailed register-based interface to exercise all features of the IC. The EV kit is compatible with any version of the MAX77859 WLP IC (MAX77859AEWO+T is the default one installed).
