描述

The MAX17673AEVKIT# evaluation kit (EV kit) provides a proven design to evaluate the MAX17673A 60V, 1.5A high efficiency, synchronous buck converter with integrated, dual 5.5V, 1A buck converters. The EV kit is preset for 5V output at a load current of up to 1.5A from the highvoltage (HV) buck converter, and 3.3V and 1.8V outputs at load currents up to 1A each from the low-voltage (LV) buck converters. The HV buck converter is programmed to operate at 400kHz, and the LV buck converters are programmed to operate at 2MHz, for optimum efficiency and component sizes. The output of the HV buck converter is connected to the input of the LV buck converters. The EV kit features adjustable input undervoltage lockout and soft-start for the HV buck converter, and power- OK (POK_) signals for all three buck converters. The MAX17673/MAX17673A IC data sheet provides a complete description of the part that should be read in conjunction with this data sheet prior to operating the EV kit.
