Compact high-efficiency 15W and 25W isolated DC-DC converters

CUI has introduced two new open-frame isolated DC-DC converter families to its power portfolio. The PRD15 and PRD25 series output 15W and 25W of power respectively from a single square inch of board space. With high typical efficiency up to 91%, the compact low-profile modules measure just 27.9mm x 24.4mm x 8.1mm (c. one square inch). The PRD15 series features a 4:1 input voltage range of 9 - 36VDC or 18 - 75VDC, while the PRD25 series provides a 2:1 input voltage range from 36 - 75VDC. 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 inch modules. For advanced systems, the output voltage of the PRD series delivers fast transient response performance and very low ripple and noise. Additionally, the series’ high efficiency and -40C to 85C operating temperature range makes them suitable for convection-cooled equipment. Target applications include microcontrollers, datacom, telecom, remote sensor systems and portable electronics. The PRD15 series is available with single regulated outputs of 3.3, 5, 12 and 15VDC, while the PRD25 offers outputs of 3.3, 5, and 12VDC. Over-voltage, over-current, under-voltage, over-temperature and short-circuit protections are also included. All units hold UL/cUL safety approvals.
