Semiconductor Circuits introduces CPE17B50 DC-DC converter.

May 6, 2016 – Semiconductor Circuits, Inc. introduces the CPE17B50 12V, 16.7A wide input range 8th brick DC-DC converter. This compact part is designed for use in bus converter applications and is intended to directly replace larger quarter bricks modules (identical pin out and functionality.) The converter features a 38-60Vdc (48Vdc nominal) input voltage and has a 12Vdc output rated at 200W. The output has a trim range of +/- 10%. The converter has a full load efficiency of 94% which allows for use over a wide ambient temperature range (w/derating.) The open frame design is also available with an optional base plate for those applications where conduction cooling is required or preferred. This module is compliant with DOSA footprint and interface standards.

The CPE17B50 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 80V/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 base plate version is available for conduction cooling applications with an industry standard height of 0.50″.
