Evaluation Kit for the MAXM17903 1.5V Output-Voltage Application

Product Details

The MAXM17903 1.5V output evaluation kit (EV kit) provides a proven design to evaluate the MAXM17903 high-voltage, high-efficiency, synchronous step-down DC-DC module. The EV kit is programmed to deliver 1.5V output for loads up to 300mA. The EV kit features an adjustable input undervoltage lockout, selectable mode, and open-drain active-low RESET signal. The MAXM17903 data sheet provides a complete description of the module that should be read in conjunction with this EV kit data sheet prior to modifying the demo circuit. For full module features, benefits and parameters, refer to the MAXM17903 data sheet.
