8th Brick DC-DC Converters for Power Amplifier Applications

CPE Series Bus ConverterLondonderry, NH – September 14, 2017 – Semiconductor Circuits, Inc. introduces the CPE6D24, CPE6R24 and CPE5R48 “Cool Power Technologies” wide input range 8th brick DC-DC converters designed for use in power radio and other applications where it is intended to directly replace larger quarter bricks modules (identical pin out and functionality.) The converter features an industry standard 18-36Vdc or 36-72Vdc (24 or 48Vdc nominal) input voltage ranges and have outputs trimmable from 21-34Vdc (model dependent – see datasheet.) The modules have a typical full load efficiency of 93% which allows for use over a wide ambient temperature range with minimal derating. The open frame design is also available with an optional baseplate for those applications where conduction cooling is required or preferred. This module is compliant with DOSA footprint and interface standards.

The CPE6D24, CPE6R24 and CPE5R48 meet EN 60950 basic insulation requirements and is UL94 V-0 flammability rated. The modules comply with all of the typical industry requirements including no load operation and 2X nominal input voltage transient capability.

Other features include: fixed-frequency operation, auto-restart OVP, OCP & OTP protections, UVLO and remote sense. Remote ON/OFF is standard with positive or negative logic options are available.

The modules feature a standard 8th brick pinout and dimensions of 2.3” L x 0.9” W (58.4mm x 22.9mm.) It has a maximum height of 11.8mm (0.465”) which accommodates tight card spacing with minimal airflow blockage of downstream components. A baseplate version is available for conduction cooling applications with an industry standard height of 0.50″.
