RECOM Power RPX-4.0 Integrated Inductor DC-DC Buck Converters

RECOM Power RPX-4.0 Integrated Inductor 4.0A DC-DC Buck Converters feature a 3.8VDC to 36VDC input range with 5V, 12V, or 24V supply voltages in a compact 5mm x 5.5mm x 4.1mm thermally enhanced QFN package. The output voltage of the RPX-4.0 buck converters can be set with two resistors in the range from 1VDC up to 7VDC. The output current is up to 4A and is fully protected against continuous short-circuits, output overcurrent, or over-temperature faults. These features make the RPX-4.0 Integrated Inductor DC-DC Buck Converters from RECOM particularly suitable for industrial automation, test and measurement, portable devices, and high-density or weight-sensitive applications.
