3.3-V, 20-A (66-W) 2:1 input 16th brick DC-DC converter delivers high performance benefits

June 22, 2012 // By Paul Buckley
Semiconductor Circuits, Inc. has introduced the CPT20F48 ‘Cool Power Technologies’ 3.3 V, 20 A wide input range 16th brick DC-DC converter.

The open frame module provides a full 66 W of 3.3 V power @ 55C & 200lfm of airflow – ideal for distributed power architecture applications or as a fully regulated intermediate bus converter. The module is compliant with DOSA footprint and interface standards and has a wide input voltage range of 36 to 75 VDC & provides 2250 VDC input to output isolation.

The CPT20F48 is a high efficiency module with efficiencies exceeding 90% from ½ load through full load. The module 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, 100 V/100 mS 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%/-20% 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 inch L x 0.9 inch W (33 mm x 22.9 mm.) The device has a maximum height of 9.5 mm (0.375 inch) which accommodates tight card spacing with minimal airflow blockage of downstream components.
