Murata release efficient 250W baseplate cooled quarter-brick DC-DC converter, now available from Anglia

http://www.anglia.com/newsarchive/115px_images/5100.jpg

Murata has announced new developments 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 250 Watt output power with a baseplate temperature in the range of -40°C to +100°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.

Features:

  • 4:1 Input voltage range of 9-36V
  • Single 12V output up to 20.5 Amps
  • Industry-standard quarter-brick footprint
  • 39.1mm x 60.7mm x 12.7mm (54" x 2.39" x 0.5")
  • 2250V isolation voltage (input-to-output)
  • Efficiency up to 93% (half-load)
  • Excellent thermal performance
  • Auto-softstart
  • 275kHz fixed switching frequency
  • Remote on/off (positive logic)
  • No minimum load requirement
  • Good shock and vibration damping
  • Operating temperature range -40°C to +100°C
  • RoHS compliant
