This technology provides developers with space-qualified power converters that help to minimize risk and lower development costs,
These SA50-120 radiation-hardened DC to DC power converters – the only standard non-hybrid space-grade DC-DC power converters available – utilize surface mount component construction, allowing flexibility and customisation in order to fit specific applications and requirements.
The device family, qualified to Mil-Std-461, Mil-Std-883 and Mil-Std-202, enables designers to start with proven COTS technology and quickly scale up development, reducing risk and development time.
SA50-120 power converters utilize 120V input and offer up to 56W of output in a low profile, small-sized solution. EMI compliant and a radiation-hardened design with single and triple outputs these converters are intended for Space Station and ORION program platforms.
The units utilize switching regulators that use peak current mode controlled single-ended forward converter topology with inherent single-event immunity.
Offering eight million hours Mean Time Between Failure (MTBF) and up to 87% efficiency – the highest of any standard 120V input space-grade DC-DC power converter - the SA50-120 maximizes system performance and reliability.
The units are qualified to 100 krad (Si) Total Ionization Dose (TID) and Single Event Effects (SEE) greater than 80 MeV cm2/mg, and offer synchronization, a Transitor-Transitor Logic (TTL) on/off command signal, and various protection features.
Single output versions additionally offer remote sense, output voltage adjust and parallel connection functions.
