4:1 Input High-Performance 16th Brick DC-DC Converter Family

Semiconductor Circuits, Inc. has added new members of its “Cool Power” product family featuring 4:1 input voltage ranges of 9 - 36 Vdc, and 18 - 72 Vdc and up to 50W output in a DOSA standard 16th brick dc-dc converter. These open frame modules are rated for 50W @ 55C & 200lfm of airflow and are suited for distributed power architecture applications or as a fully-regulated intermediate bus converter. These modules are compliant with DOSA footprint and interface standards and provide 2250 Vdc input to output isolation. Output voltages of 3.3-, 5-, 12- and 15-Vdc are available. Custom values are also being manufactured for particular industries such as solar power, aircraft and PoE communications.

The CPT series is a high efficiency module product family with efficiencies exceeding 90% from 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 & OTP protections, UVLO, remote sense and +10%/-20% output voltage trim using industry standard equations. Remote ON/OFF is standard with positive or negative logic options available. This product set features standard 16th brick pinout and dimensions of 1.3” L x 0.9” W (33mm x 22.9mm.) It has a maximum height of 9.5mm (0.375”) which accommodates tight card spacing with minimal airflow blockage of downstream components.
