Efficient 1kW DC-DC Converter For Industrial And Battery Apps


Murata has claimed the industry’s highest power density full brick modular DC-DC converter with a 9V-36Vin range ideally suited for battery operated and Industrial 12V & 24V systems needing 1kW of power. Typical applications include powering motor drive systems, emergency vehicle electronics, smart grid, and heavy-duty truck power bus solutions.

The new ICF series converters are 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%. They offer two output voltage options (24 VDC or 28 VDC) and is packaged in an enclosed industry-standard full-brick package.

The converters follow the same design principles as the previously introduced members to provide an industrial grade, rugged, high-power, baseplate-cooled DC-DC converter, the firm says.

The first in the series was the industry-leading ICQ 250W quarter-brick announced in September 2016, followed by the ICH 360W & 500W half-brick modules in October 2016.


The ICF series converters meet EN60950, UL/CSA safety requirements for embedded power modules. A Basic insulation system provides galvanic input-to-output isolation rated at 2250VDC.

Measuring 4.7 x 2.5 x 0.52 inches, the converter’s specially designed package/baseplate 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, says the firm.

The series features a high efficiency of 96.4%, keeps energy consumption to a minimum in standby, and ensures stable operation in low load conditions. The firm also offers modules with an extended temperature range down to -55°C for special order.

The modules come with a positive logic remote On/Off control as the standard configuration. Protection features include input transient to 50VDC, over-temperature shutdown, output over-current, and input under-voltage lockout.
