50W 4:1 Input 16th Brick DC-DC Converters

Press release date: May 14, 2014

Atkinson, NH -- Semiconductor Circuits, Inc. introduces the new "Cool Power Technologies" ultra-wide input range 16th brick DC-DC converter series. These open frame modules provide up to 50W of output power @ output voltages of 1.8, 3.3, 5.0, and 12Vdc – ideal for distributed power architecture applications or as a fully regulated intermediate bus converter. These modules are compliant with DOSA 16th brick footprint and interface standards. It has a wide input voltage range of 9 to 36 VDC & provides 2250 VDC input to output isolation.

The CPT 4:1 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 startup.

Other features include: fixed-frequency operation, auto-restart OVP, OCP & OTP protections, UVLO, remote sense and +/-10% 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 1.3" L x 0.9" W (33.02mm x 22.86mm.) It has a maximum height of 0.37" (9.4mm) which accommodates tight card spacing with minimal airflow blockage of downstream components.
