CUI Inc has added two open-frame isolated DC-DC converter families to its portfolio of power-converter products.

The PRD15 converters produce an output of 15W, and the output of the PRD25 converters is 25W. Featuring high typical efficiency up to 91%, these compact modules measure just 27.9mm x 24.4mm x 8.1mm – a board footprint of just one square inch.

The PRD15 series features a choice of 4:1 input-voltage ranges, either 9V to 36V DC or 18 to 75V DC, while the PRD25 series provides a 2:1 input-voltage range of 36V-75V DC. The PRD15 series is available with single regulated outputs of 3.3V, 5V, 12V or 15V DC, while the PRD25 offers outputs of 3.3V, 5V or 12V DC.

Both series are available in through-hole and surface-mount versions. The converters’ industry-standard pin-outs make them ideal replacements for larger 1” x 2” modules. In addition, the series’ high efficiency and operating-temperature range of -40°C to 85°C make them suitable for convection-cooled equipment.

Over-voltage, over-current, under-voltage, over-temperature and short-circuit protections are included.
