Product Details

The MAX77505 evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) that demonstrates the MAX77505 hysteretic step-down (buck) converter. The EV kit is a step-down voltage regulator circuit using the MAX77505 that is capable of a 2.5V to 16V input, 3A of continuous load, and an adjustable output voltage between 0.8V to 5.5V using an R_SEL resistor between the SEL pin and GND.
