Baseplate-cooled half-brick DC-DC converter runs up to 500W

October 20, 2016 // By Nick Flaherty
Murata is developing a new class of DC-DC half brick converter modules for industrial applications.

The ICH series of industrial grade, isolated DC-DC converters provide highly efficient, baseplate-cooled power from 360 W up to 500 W from an industry-standard half-brick package measuring 2.40 x 2.50 x 0.52 inches (61.0 x 64.0 x 13.2 mm).

The ICH series was designed for rough service or industrial applications and incorporates features such as a wide 4:1 input voltage range, from 9 to 36 VDC, and a specially designed package/baseplate that allows conduction cooling for improved thermal performance including closed-box applications. These highly efficient converters, typically up to 95.7% for the 500 Wt unit, are available in three single-output models providing regulated 12, 24, or 28 VDC. The electrical and mechanical design allows the ICH series to deliver the full power rating with a baseplate temperature of -40°C to +105°C without derating. In addition, the ICH is designed to meet the environmental stress limits for shock & vibration specified in MIL–STD810G throughout its service life.

The ICH series achieves its high performance by incorporating proprietary circuit architectures, advanced packaging, and thermal design advances. The outputs are fully isolated from the input supply, allowing flexibility for various grounding requirements or for creating positive or negative outputs. Galvanic input to output isolation rated at 2250 VDC, incorporating a Basic insulation system, are standard across all models. The ICH series has been designed to meet EN60950, UL/CSA safety requirements for imbedded power modules.
