High efficiency 1 kW full-brick DC-DC converter is baseplate cooled

November 17, 2016 // By Nick Flaherty
Murata has launched its third modular DC-DC converter development effort for industrial 12 V and 24 V systems needing 1kW of power.

The ICF series follows the same design principles as the previous modules to provide an industrial grade, rugged, high-power, baseplate-cooled DC-DC converter. Capable of delivering up to 1,000 Watts from an input source of 9 to 36 VDC with a typical efficiency rating of 96.4%, the ICF series offers two output voltage options (24 VDC or 28 VDC) and is packaged in an enclosed industry-standard full-brick package.

Measuring 119.0 x 64.0 x 13.2 mm (4.7 x 2.5 x 0.52 inches), the converter is enclosed in a specially designed package/baseplate that meets the environmental stress limits for shock and vibration specified in MIL-STD-810G, while offering full power with a baseplate operating temperature range of -40 °C to 105 °C without derating.

The ICF series achieves its high performance by incorporating proprietary circuit architectures, advanced packaging, and thermal design advances. Accommodating an input voltage range of 9 to 36 VDC, two single output models are available, providing a nominal 24 or 28 VDC regulated output. 

The outputs are fully isolated from the input supply, allowing flexibility for various grounding requirements or for creating positive or negative outputs. A Basic insulation system provides galvanic input-to-output isolation rated at 2250 VDC that is provided across all models. The ICF series has been designed to meet EN60950, UL/CSA safety requirements for embedded power modules. The industry-standard full-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.
