High-efficiency synchronous step-down DC-DC switching power module demo kit

Available now from Mouser stock, the Maxim MAXM17543EVKIT an evaluation / demonstration circuit of the MAXM17543 high-efficiency, synchronous step-down DC-DC switching power module. The evaluation kit is designed for a 3.3V output and delivers up to 2.5A load current. It offers a wide input-voltage range of 4.5V to 42V. The kit switches at an optimal 500kHz switching frequency to allow the use of small component-sizes. This helps to minimize solution-size while maintaining high-performance. The evaluation kit provides a precision-enable input, and an open-drain active-low RESET output signal. With external frequency synchronization, this provides a simple and reliable start-up sequence and eliminate beat frequency between regulators. Applications include base station point-of-load regulators, distributed supply regulation, PGA and DSP point-of-load regulators, HVAC and building control and industrial power supplies.
