Semiconductor Circuits has expanded the power rating of its Cool Power Technologies wide input range 16th-brick DC-DC converter series. The open-frame modules provide up to 100W of output power at output voltages of 2.5, 3.3, 5, and 12VDC making them ideal for distributed power architecture applications or as a fully-regulated intermediate bus converter. The modules are compliant with DOSA 16th-brick footprint and interface standards. The converters have a wide input voltage range of 18VDC to 36VDC or 36VDC to 75VDC and provide 2250VDC input to output isolation. The CPT 2:1 input series meets EN 60950 basic insulation requirements and is UL94 V-0 flammability rated. The module complies with all of the typical industry requirements including no load operation, 2X nominal input voltage transient and pre-biased load start-up. 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. The modules feature a standard 16th- brick pinout with dimensions of 33.02mm x 22.86mm. They have a maximum height of 10.3mm which accommodates tight card spacing with minimal airflow blockage of downstream components, says the company.
