36W 32nd-Brick Bus Converter Delivers 12Vdc

Semiconductor Circuits, Inc. introduces the new Cool Power Technologies 36W wide input range 32nd brick dc-dc converter series. These open frame modules provide 36W of output power at 12Vdc, suitable for distributed power architecture applications or as a fully-regulated intermediate bus converter. These modules are compliant with DOSA 32nd-brick footprint and interface standards. It has a wide input voltage range of 18- to 36-Vdc or 36- to 75-Vdc and provides 1500-Vdc input-to-output isolation. Other standard modules in the 2:1 series are available that deliver 3.3Vdc at 8A and 5Vdc at 6A.

The CPZ 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, 100V/100mS 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 32nd-brick pinout with dimensions of 0.76" L x 0.92" W (19.3mm x 23.4mm.) It has a maximum height of 0.35″ (8.9mm) 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.
