描述

The MAX17703EVKITA# (EV kit) provides a proven design to evaluate the MAX17703 high-efficiency, highvoltage, Himalaya synchronous step-down DC-DC Li-ion charger controller. The EV kit charges the Li-ion battery in constant current (CC) and constant voltage (CV) states and terminates in a topup-charge state after the taper timer is elapsed. The EV kit is designed to charge the Li-ion battery with 10A CC mode charging current (ICHGMAX) and 4.2V CV mode voltage (VOUT) from an 8.5V to 60V input supply. The EV kit is optimized for a 24V nominal input 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 CC mode and CV mode charging time. The EV kit also features battery temperature sensing and charges only when the temperature is in the allowable charging temperature range. For more details about the IC benefits and features, refer to the MAX17703 IC data sheet.
