IR has DC/DC converters for satellite power systems

International Rectifier has announced the M3G120 series of RAD-hard, 120V input DC/DC converters.

The devices are suitable for a range of digital and analogue satellite power systems requiring up to 15 years or more of mission life. They include a range of reliability and 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 of over 200krad (Si), single event effect with rated LET greater than 83MeVcm²/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. The DC/DC converters also feature 95 to 140V DC input, up to 160V input transients, input under-voltage protection, synchronisation input/output and on/off control via converter's Inhibit pin and Class K hybrid MIL-PRF-38534 qualified.
