The M3G120 series of 40 W radiation-hardened (rad-hard) 120V input DC-DC converters from International Rectifier (IR) are designed for a range of analog and digital satellite power systems. The converters are targeted at satellite systems requiring long mission life (15 years or more), such as NASA’s Orion Multi-Purpose Crew Vehicle (MPCV) programs and space stations. The M3G120 series is based on IR’s M3G legacy series, which has been used in the space industry since 1998.

The DC-DC converters are lightweight – less than 110g included in a 3.5" x 2.5" x 0.475" package (including I/O pins and mounting tabs). The converters are available in single and dual output configurations, and feature standard single output voltages of 3.3, 5, 12, 15, and 28V and dual output voltages of ±5V, ±12V, and ±15V. Features of the M3G120 series include: 95V to 140V DC input; integrated EMI filter; input under-voltage protection; input/output and on/off control via converter’s inhibit pin; single event effect (SEE) (Heavy Ions) with rated LET greater than 83 MeV-cm./mg; synchronization; total ionizing dose (TID) of over 200 krad (Si); and as much as 160V input transients. The converters are also Class K hybrid MIL-PRF-38534 qualified.
