February 7, 2012 - Semiconductor Circuits introduces the CPTXX36 “Cool Power Technologies” 40W 18-75V input range DC-DC converter. This 16th brick open frame module provides a full 40W of output power - ideal for distributed power architecture applications or as a fully regulated intermediate bus converter. This module is compliant with DOSA footprint and interface standards. It is available in three standard output voltages of 3V3, 5V & 12V. The high efficiency of the CPTXX36 allows operation over a wide ambient temperature range with minimal derating.
The 5V, 8A (CPT8A36N) model has full load efficiencies of 90% @ 48Vin & 91% @ 24Vin which allows full rated power @ 70°C & 100LFM (0.5 m/s) airflow @ 48Vin. It meets EN 60950 basic insulation requirements and is UL94 V-0 flammability rated. This 16th brick is designed to meet Class B conducted emissions per FCC and EN55022 specifications when used with specified external filter. The unit 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 module features a standard 16th brick pinout and dimensions (1.3” L x 0.9” W (30mm x 22.9mm)) & has a maximum height of 9.5mm (0.374”) which accommodates tight card spacing with minimal airflow blockage of downstream components.
