IR introduces M3G120 series of 40W radiation-hardened 120V input DC-DC converters for satellite power systems
International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today announced the introduction of the M3G120 Series of 40W radiation-hardened (RAD-Hard) 120V input DC-DC converters for a wide range of digital and analog satellite power systems requiring up to 15 years or more of mission life such as space stations and NASA’s Orion MPCV (Multi-Purpose Crew Vehicle) programs.
The M3G120 series was developed using a proven design methodology based on the legacy of the M3G Series and extensive space design heritage. The design included a selection of established reliability and known radiation performance components fully de-rated to NASA EEE-INST-002 and MIL-STD-1547B requirements. Available in single and dual output configurations, the DC-DC converters feature standard single output voltages of 3.3, 5, 12, 15, and 28V and dual output voltages of ±5V, ±12V and ±15V. Key features include total ionization dose (TID) of over 200 krad (Si), single event effect (SEE) (Heavy Ions) with rated LET greater than 83 MeV-cm²/mg, integrated EMI filter, and light weight of less than 110g in a compact hermetic 3.5” x 2.5” x 0.475” package including I/O pins and mounting tabs.
