16th brick offers usable power to 100 W

The CPT 16th brick dc/dc converter series open-frame modules can now be ordered with a base plate heat spreader to provide up to 100 W of usable output power at output voltages of 2.5, 3.3, 5.0, 12, and now 24 Vdc. The converters suit distributed power architecture applications or as a fully regulated intermediate bus converter.

The modules are compliant with DOSA 16th brick footprint and interface standards. They have an input voltage range of 2:1 input up to 100 W and 4:1 input up to 50 W and provide 2,250-Vdc 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, and 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 x 0.9 (33.02 x 22.86 mm). They have a maximum height of 0.374 in. (9.5 mm) to accommodate tight card spacing with minimal airflow blockage of downstream components. Base plate modules offer a standard 0.500-in. height (12.7 mm) for interfacing with heat-spreader/chassis surfaces. A heat sink can be attached to the module using optional M3 threaded holes in base plate.
