Description

The MAXM17544 evaluation kit (EV kit) is a demonstration circuit of the MAXM17544 high-voltage, high-efficiency, current-mode scheme, synchronous step-down, DC-DC switching power module. The EV kit is designed for a 3.3V output and delivers up to 3.5A load current from a wide input-voltage range of 4.5V to 42V. The EV kit switches at an optimal 500kHz switching frequency to allow the use of small component-sizes, helping to 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 MAXM17544 IC 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.
