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.
