IR – Hybrid Hi-Rel Radiation Hardened DC/DC Converter (M3GB50)

IRF-HiRelIR’s M3GB50 is available with an input voltage of 50V and an output voltage of:

  • 12V dual
  • 5V dual
  • 15V dual
  • 5V single
  • 3 V single

The M3GB-Series of DC-DC converters are second generation design of the legacy M3G-Series product family but with enhanced overall performance. M3GB-Series is form, fit and functional equivalent to the first generation M3G-Series. It is designed to be backward compatible to the M3G-Series with the addition of an output voltage adjustment pin for the single output models. Much the same as the original M3G-Series, these converters are radiation hardened, high reliability converters designed for extended operation in hostile environments.  Their small size and low weight make them ideal for applications such as geostationary earth orbit satellites and deep space probes. They exhibit a high tolerance to total ionizing dose, single event effects and environmental stresses such as temperature extremes, mechanical shock, and vibration.
