250W from baseplate cooled quarter-brick DC-DC

New Products |
Murata has added to its Industrial Class DC-DC converter modules with a 250W isolated DC-DC quarter-brick converter, the ICQ series. These highly efficient converters, typically 92%, are claimed as the only power modules to offer 250W output power from a quarter-brick format with a 4:1 (9 to 36 VDC) Vin range.

The ICQ series is designed for rough service/industrial applications and incorporates features such as a specially designed enclosed package that uses baseplate cooling to improve thermal performance. The electrical and mechanical design allows the ICQ series to deliver the full 255W output power with a baseplate temperature in the range of -40 to +90°C without derating. The package is designed to meet the environmental stress limits for shock and vibration specified in MIL-STD-810G throughout its service life.


Accommodating a wide 4:1 input voltage range for operation from 9 to 36 VDC, the initial ICQ delivers a regulated 12 VDC output rated at 20A and provides a basic insulation system for galvanic I/O isolation rated at 2.500 VDC. The ICQ has been designed to meet EN60950, UL/CSA safety requirements for embedded power modules. Its standard quarter-brick package measures 39.1 x 60.7 x 12.7 mm and can be deployed a drop-in replacement for lower power less efficient converters.
