CUI has announced two open frame isolated DC/DC converter families offering 15 and 25W of output power in a single square inch of board space. The PRD15 and PRD25 series feature high typical efficiency up to 91% in compact low-profile modules measuring just 27.90x24.40x8.10mm (1.10x0.96x0.32").

The PRD15 series features a 4:1 input voltage range of 9-36 or 18-75VDC, while the PRD25 series provides a 2:1 input voltage range of 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 1x2” 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 -40 to +85°C operating temperature range makes them suitable for convection-cooled equipment. Target applications for the PRD15 and PRD25 series include MCUs, datacomms, telecomms, 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.

The PRD15 and PRD25 are available immediately through distribution with prices starting at $23.51 each in 100 unit quantities; please contact CUI for OEM pricing.
