Datasheet

Semiconductor Circuits, Inc. introduces the CPT20F48 “Cool Power Technologies” 3.3V, 20A wide input range 16th brick DC-DC converter. This open frame module provides a full 66W of 3.3V power @ 55C & 200lfm of airflow – 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 has a wide input voltage range of 36 to 75VDC & provides 2250VDC input to output isolation.

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