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

MUR391_icf-prMurata is announcing the third modular DC-DC converter development effort from Murata Power Solutions designed for industrial 12 & 24 VDC systems. The ICF series follows the same design principles 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 × 64.0 × 13.2 mm (4.7 × 2.5 × 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.

Typical applications include 12 or 24 VDC battery systems, powering motor drive systems, emergency vehicle electronics, smart grid, and heavy-duty truck power bus solutions. The ICF series has no minimum load requirement, keeping energy consumption to a minimum when the end device is in standby as well as ensuring stable operation in low load conditions. All modules come with a positive logic remote On/Off control as the standard configuration, along with full protection features including input transient to 50 VDC, over-temperature shutdown, output over current, and input under-voltage lockout.

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