Description

The RPX-2.5 is a buck converter with integrated inductor in a tiny 4.5mm x 4mm x 2mm thermallyenhanced QFN package (the smallest in its class). The input range is from 4.5 to 28VDC, allowing 5V, 12V or 24V supply voltages to be used. The output voltage can be set with two resistors in the range from 1.2V up to 6V. The output current is up to 2.5A and is fully protected against continuous short-circuits, output overcurrent or over-temperature faults. The enable pin features an internal pull-up current source, so will operate with open-drain, open-collector, logic gate or switched inputs (leave open if not used).
