Radiation-hardened power converters Microchip Technology is expanding its SA50-120 power converter family with nine new units based on its Commercial Off-the-Shelf (COTS) technology. 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 â the only standard non-hybrid space-grade DC-DC power converters available â 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.
