100W DOSA Sixteenth Bricks with 2:1 Input Range

Semiconductor Circuits, Inc. has increased usable power in its "Cool Power Technologies" 16th brick dc-dc converter series. These open-frame modules can now be ordered with a base plate heat spreader to provide up to 100W of usable output power at output voltages of 2.5, 3.3, 5.0, 12 and now 24Vdc – suited 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. These converters have a wide input voltage ranges of 2:1 input up to 100 Watts and 4:1 inputs up to 50 Watts (up to 75W coming) and provide 2250Vdc input to output isolation.

The CPT series meets UL/EN 60950 safety standard requirements and is UL94 V-0 flammability rated. All modules are ROHS II and REACH compliant. The modules also meet 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 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.) They have a maximum height of 0.374″ (9.5mm) which accommodates tight card spacing with minimal airflow blockage of downstream components. Base plate modules offer a standard 0.500″ inch height (12.7mm) for interfacing with heat spreader/chassis surfaces. A heat sink can be attached to the module using optional M3 threaded holes in base plate.
