ICH Series : Efficient 360-500W baseplate-cooled half-brick DC-DC converter

Date: Oct 19, 2016

ICH Series : Efficient 360-500W baseplate-cooled half-brick DC-DC converterMurata is announcing a new development effort for industrial class DC-DC half brick converter modules from Murata Power Solutions. The ICH series of industrial grade, isolated DC-DC converters provide highly efficient, baseplate-cooled power from 360 Watts up to 500 Watts 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 Watt 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 embedded power modules.

The industry standard half-brick enclosed package has been specially designed to meet the demands of rugged operating environments and complies with the MIL-STD-810G standard for functional shock and vibration. Typical applications include 12 or 24V battery systems, powering motor drive systems, emergency vehicle electronics, smart grid, and heavy-duty truck solutions. The entire ICH series has no minimum load requirements, helping to maintain a stable operation and conserve energy consumption in customer applications. The units can operate over the temperature range from -40 to +105°C. Models with an extended temperature range down to -55°C are available for special order.

All models come with a positive logic remote On/Off control as the standard configuration, along with full protection features including input transient to 50VDC, over temperature shutdown, output over current, and input under voltage lockout.

The ICH series is scheduled for production release in January 2017; pre-production samples are available upon request.
