Full-Brick DC/DC Converter Delivers Highest Power Density

08 December 2016

Eyeing battery-operated and industrial applications, Murata Power Solutions has launched a 1 kW isolated full-brick with very high power density and up to 96.5% efficiency. In fact, according to Murata, the power density offered by the 1 kW full-brick converter is the highest in the industry. A new member of the company’s ICF series, it features 4:1 input range of 9–36 V with single DC output of 24 V or 28 V. Employing the same design principles used in the industry-leading quarter-bricks and half-bricks, the full-brick converter provides an industrial-grade, rugged, high-power, baseplate-cooled DC/DC solution, said Murata.

Offering 4:1 input range, Murata’s 1 kW full-brick DC/DC converter provides single regulated 24 VDC or 28 VDC output.   Offering 4:1 input range, Murata’s 1 kW full-brick DC/DC converter provides single regulated 24 VDC or 28 VDC output. Housed in a specially designed package measuring 119 × 64 × 13.2 mm (4.7 × 2.5 × 0.52 inches) with baseplate, the converter meets the environmental stress limits for shock and vibration as per MIL-STD-810G specifications, while offering full power. The baseplate operating temperature range is –40° C to +105° C. In addition, it also complies with EN60950, UL/CSA safety requirements for embedded power modules, and provides galvanic input-to-output isolation of 2,250 VDC.

Other features include positive logic remote on/off control; input transient to 50 VDC; protection against over-temperature; and output over-current and input under-voltage lockout. To ensure stable operation in low load conditions, the converter has no minimum load requirement, and keeps power consumption to a minimum in standby mode. The manufacturer has achieved this performance by combining novel circuit architecture with synchronous rectification, advanced packaging and cutting-edge thermal design. It operates at a fixed frequency of 400 kHz.

Murata said the full-brick converter is scheduled for production release in January 2017. However pre-production samples are available upon request.
