Sixteenth-Bricks Deliver 100W in DOSA Footprint

Semiconductor Circuits, Inc. has extended the power rating of the “Cool Power Technologies” wide input range sixteenth-brick dc-dc converter series. These open frame modules provide up to 100W of output power with output voltages of 2.5-, 3.3-, 5.0-, and 12-Vdc. They are targeted for use in distributed power architecture applications or as a fully regulated intermediate bus converter. These modules are compliant with DOSA sixteenth-brick footprint and interface standards. These converters have a wide input voltage range of 18- to 36-Vdc or 36- to 75-Vdc and provide 2250-Vdc 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 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.

The modules feature a standard sixteenth-brick pinout with dimensions of 1.3" L x 0.9" W (33.02mm x 22.86mm.) They have a maximum height of 0.404″ (10.3mm) which accommodates tight card spacing with minimal airflow blockage of downstream components. Other output voltages in the 4:1 input series are available upon request.
