MAY 12, 2010 -- Semiconductor Circuits Inc. introduces the CPT7B48 “Cool Power Technologies” 12V, 7A 16th brick DC-DC converter. This open frame module provides 84W of 12V power @ 55C & 200lfm of airflow, well suited for distributed power architecture applications or as a regulated intermediate bus converter. This module is compliant with DOSA footprint and interface standards. It has a wide input voltage range of 36 to 75VDC and provides 2250VDC input to output isolation.
The CPT7B48 is a high-efficiency module with efficiencies exceeding 93 percent from half load through full load. It meets EN 60950 basic insulation requirements and is UL94 V-0 flammability rated. The module complies with all 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 and OTP protections, UVLO with 2V hysteresis, remote sense and +10/-20 percent 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 of 1.3 L x 0.9 W inches (22.9mm x 33mm.) It has a maximum height of 9.5mm (0.375 inch) which accommodates tight card spacing with minimal airflow blockage of downstream components.
