40W rad-hard dc/dc converters suit satellites

The M3G120 series of 40-W radiation-hardened 120-V input dc/dc converters suit digital and analog satellite power systems requiring 15 years of mission life. They target space stations and NASA’s Orion MPCV (Multi-Purpose Crew Vehicle) programs.

The converter design includes radiation performance components de-rated to NASA EEE-INST-002 and MIL-STD-1547B requirements. Available in single and dual output configurations, the converters feature standard single output voltages of 3.3, 5, 12, 15, and 28 V and dual output voltages of ±5, ±12 and ±15 V. 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 weight of less than 110g in a compact hermetic 3.5 x 2.5 x 0.475-in. package. Pricing begins at $15,750 ea/5.
