Dc-dc converters from International Rectifier are 50-W devices that maximize efficiency for onboard spacecraft applications requiring mission lives up to 15 years. The GH Series of radiation-hardened devices is suitable for designs using digital signal processors and field-programmable gate array technologies that require a supply voltage as low as 1.0 V. Features include 18 V to 40 V input range, total ionization dose of over 100 krad (Si), single event effect (heavy ions) with rated linear energy transfer greater than 82 MeV-cm²/mg, internal electromagnetic interference filter complying with most major satellite power buses, and a mass of less than 110 g.
