Semiconductor Circuits, Inc. introduced the CPT7A18 "Cool Power Technologies" 5V, 8A wide input range 16th brick DC-DC converter. This open frame module provides a full 40W of 5V 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 9 to 36VDC & provides 1500VDC input to output isolation.

The CPT7A18 is a high efficiency module with efficiencies exceeding 87% 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, 50V/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 (22.9mm x 33mm.) It has a maximum height of 9.5mm (0.375”) which accommodates tight card spacing with minimal airflow blockage of downstream components.
