IR HiRel high temperature DC-DC converters are designed for high power subsurface applications up to 185°C including down-hole drilling, seismic and natural resource exploration equipment.

IR HiRel high temperature DC-DC converters are well suited as building blocks and intermediate bus converters for power systems. Available as commercial off-the-shelf (COTS), the high temperature converters significantly reduce design cycles and design costs associated with high temperature engineering.

IR HiRel high temperature DC-DC converters use a conservative design approach inspired from HiRel space and military expertise and hermetic, hybrid package construction and process to deliver functionality up to high continuous operating case temperature and to survive high shock environment. Hybrid converters can provide the same power in a smaller size than typical PCB designs, allowing more functionality in the same tool size. Hermetic converters offer higher reliability in a high temperature and high shock environment.

 

Features:

  • Internal EMI filter
  • Magnetic coupled feedback
  • 100MOhms @ 500VDC isolation
  • Under-voltage lockout
  • Frequency synchronization
  • Short circuit and overload protection
  • External Inhibit
  • Trimmable output voltage (single output)
  • Stackable to achieve higher output power

High Temperature Converters Key Benefits:

  • Well characterized performances under the temperature extremes without power de-rating
  • Designed for high voltage applications
  • Thermal management using proprietary package design
  • Low noise design to facilitate system integration
  • Qualified high temperature processes for long term mechanical integrity and reliability
  • Designed to operate through severe shock and vibration environments
