MAX17701EVKITAE#

MAX17701EVKITAE# is an evaluation kit which provides a proven design to evaluate the MAX17701 high-efficiency, high-voltage, Himalaya synchronous step-down DC-DC supercapacitor charger controller. The EV kit provides constant current (CC) mode and constant voltage (CV) modes to charge supercapacitors. The EV kit is designed to deliver 20A CC mode current (ICHGMAX) and 5V CV mode voltage (VOUT) from a 7.1V to 60V input supply. The EV kit supports up to continuous 10A load connected in parallel to supercapacitors at the output. The EV kit is optimized for 24V nominal input voltage application. The switching frequency of the EV kit is set at 350kHz (fSW) for optimum efficiency and component size. The EV kit features a safety timer (TMR) to set the maximum allowed constant current (CC) mode charging time.
