MAX17702EVKITA# provides a proven design to evaluate the MAX17702 high-efficiency, high voltage, Himalaya synchronous step-down DC-DC lead acid (Pb-acid) charger controller. The EV kit charges the Pb-acid battery in constant current (CC), absorption constant-voltage (CV) states, and enters an floating CV state after detecting the taper current threshold or absorption CV timer timeout in the absorption CV state. The EV kit is designed to charge the Pb-acid battery with 10A CC mode charging current (ICHGMAX) and 13.8V absorption CV voltage (VOUT) from a 19V to 60V input supply. 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 an absorption CV timer (TMR) to set the maximum charging time in the absorption CV state. The EV kit features battery temperature sensing and charges only when the temperature is in the allowable charging temperature range.
