Semiconductor Circuits Press Release

For Immediate Release

30V, 4.65A 2:1 Input High Performance
8th Brick DC-DC Converter for Power Amplifier Applications

CPE Series Bus ConverterAtkinson, NH – September 22, 2015 – Semiconductor Circuits, Inc. introduces the CPE5R48 “Cool Power Technologies” 30V, 4.65A wide input range 8th brick DC-DC converter. This compact part is designed for use in power radio applications and is intended to directly replace larger quarter bricks modules (identical pin out and functionality.) The converter features an industry standard 36-72Vdc (48Vdc nominal) input voltage and has a 30Vdc output rated at 140W. The output has an ultra-wide trim range of 21 to 34Vdc which allows for significant flexibility in various power amplifiers designs. The converter has a 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 CPE5R48 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 and 100V/100mS input voltage transient.

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 available.

The module features 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″.
