DC to DC Power Supplies (Converters)
Quarter-Brick DC/DC Converter offers efficient design, operation.
Press Release Summary:
Delivering 92% typ efficiency, ICQ series offers 250 W of output power from quarter-brick format 1.54 x 2.39 x 0.50 in. with 4:1, 9–36 Vdc input range. Enclosed package uses baseplate cooling to maximize thermal performance, while electrical and mechanical design allows delivery of full 225 W output power from -40 to +90°C without derating. Designed to meet environmental stress limits for shock and vibration in MIL-STD-810G, fully protected series provides positive logic remote On/Off control.
Original Press Release:
Efficient 250W Baseplate Cooled Quarter-Brick DC-DC Converter
Murata is announcing a new development effort for Industrial Class DC-DC converter modules. The first in this series is a 250 Watt isolated DC-DC quarter-brick converter, the ICQ series from Murata Power Solutions. These highly efficient converters, typically 92%, are believed to be the only power modules on the market to offer 250 Watts of output power from a quarter-brick format with a 4:1 (9 to 36 VDC) Vin range. The ICQ series is designed for rough service/industrial applications and incorporates features such as a specially designed enclosed package that uses baseplate cooling to improve thermal performance. The electrical and mechanical design allows the ICQ series to deliver the full 225 Watt output power with a baseplate temperature in the range of -40 to +90°C without derating. In addition, the ICQ is designed to meet the environmental stress limits for shock and vibration specified in MIL-STD-810G throughout its service life. The ICQ0120V1PC achieves its high performance by incorporating proprietary circuit architectures, synchronous rectification, advanced packaging, and thermal design approaches.
Accommodating a wide 4:1 input voltage range for operation from 9 to 36 VDC, the initial ICQ delivers a regulated 12 VDC output rated at 20 A and provides a basic insulation system for galvanic I/O isolation rated at 2,500 VDC. The ICQ has been designed to meet EN60950, UL/CSA safety requirements for embedded power modules.
The industry-standard quarter-brick package measures 39.1 mm x 60.7 mm x 12.7 mm (1.54 x 2.39 x 0.50 inches) and is ideal as a drop-in replacement for lower power, less efficient converters.
All models come with a positive logic remote On/Off control as the standard configuration, and full protection features including input transient protection to 50 VDC, over temperature shutdown, output over current, and input under voltage lockout.
The ICQ series is scheduled for production release in January 2017; pre-production samples are available upon request.
