DC-DC converters for distributed power systems introduced by Semiconductor Circuits

ATKINSON, N.H., 6 Aug. 2013. Semiconductor Circuits Inc. in Atkinson, N.H., is introducing members of its Cool Power DC-DC converter family with a 4:1 input voltage ranges of 9 to 36 volts DC, and 18 to 72 volts DC and as much as 50 Watts output in a DOSA standard 16th brick DC-DC converter.

These open-frame power electronics power electronics modules provide as much as 50 Watts of output power at 55 degrees Celsius and 200 linear feet per minute of airflow for distributed power architecture applications or as a regulated intermediate bus converter.

These modules comply with DOSA footprint and interface standards and provide 2,250 volts DC input to output isolation. Output voltages of 3.3, 5, 12, and 15 volts DC are available. Custom values also are being manufactured for particular industries such as solar power, aircraft. and POE communications.

The CPT series offers efficiencies exceeding 90 percent from one-half load through full load. They meet EN 60950 basic insulation requirements and are UL94 V-0 flammability rated. Safety certification by TUV has been granted for some members of the family and the remaining ones are in the certification process.

The modules comply with typical industry requirements including no load operation, 2 X nominal input voltage transient and pre-biased load startup.

Other features include: fixed-frequency operation, auto-restart OVP, OCP and OTP protections, UVLO, remote sense and +10 percent/-20 percent output voltage trim using industry standard equations. Remote ON/OFF is standard with positive or negative logic options available.

This product has standard 16th brick pinout and dimensions of 1.3 by 0.9 by 0.9 inches. It has a maximum height of 0.375 inches high to accommodate tight card spacing with minimal airflow blockage of downstream components.
