INTERNATIONAL RECTIFIER GH Series of radiation hardened (RAD-Hard) 50W dc-dc converters maximize efficiency for onboard spacecraft applications requiring long mission life up to 15 years. Devices are suitable for designs using new digital signal processors and FPGA technologies that require a supply voltage as low as 1.0 V. Key features include 18 to 40V input range, total ionization dose (TID) of over 100krad (Si), single event effect (SEE) (Heavy Ions) with rated LET greater than 82 MeV.cm2/mg, internal EMI filter complying with most major satellite power buses, and a weight of less than 110 g.
