September 23, 2013 - Semiconductor Circuits updates CPE series dc-dc converters. Updates include a 4:1 input voltage ranges of 9 – 36 Vdc, and 18 - 72 Vdc and up to 96 Watts output in a DOSA standard 1/8th brick DC-DC converter. These open frame modules provide up to 96 Watts of output power @ 55C & 200lfm of airflow – ideal 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, 15 and 24Vdc are available. Custom values are also being manufactured for particular industries such as Solar Power, Aircraft and POE communications. The CPE series is a high efficiency module product family with efficiencies exceeding 90% from ½ 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 most 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 1/8th brick pinout and dimensions of 2.3” L x 0.9” W (58.4mm x 22.9mm.)
It has a maximum height of 10.3mm (0.404”) which accommodates tight card spacing with minimal airflow blockage of downstream components.
