The MAXM17504 evaluation kit (EV kit) is a demonstration circuit of the MAXM17504 high-voltage, high-efficiency, current-mode scheme, synchronous step-down DC-DC switching power module. The MAXM17504 EV kit is designed for 5V output and delivers up to 3.5A load current from a wide input voltage range of 11V to 60V. The EV kit switches at an optimal 500kHz switching frequency to allow the use of small component sizes that help minimize solution size while maintaining high performance. The EV kit provides a precision-enable input, an open-drain active-low RESET output signal, and external frequency synchronization to provide a simple and reliable startup sequence and eliminate beat frequency between regulators. The EV kit also includes optional component footprints to program different output voltages, an adjustable input undervoltage-lockout, and a soft-start time to control inrush current during startup. The MAXM17504 data sheet provides a complete description of the part that should be read in conjunction with this evaluation kit data sheet prior to modifying the demo circuit.
