The SA50-28 is an Isolated DC-to-DC converter capable of delivering up to 50W of output power in a small size design. The SA family provides a radiation hardened option with top class TID and SEE performance for space and military applications. With forward converter topology and a patented magnetic feedback, the SA50-28 is optimized for applications where isolated DC voltage conversion is required. The discrete surface mount design facilitates customization with reasonable lead time and modest NRE cost. To achieve MIL-STD-461 EMI compliance, an external filter is required. Off the shelf filters such as Microchip’s SF200-28-28S are available. As the only non-hybrid space grade DC-DC power converter module in the market, the SA50-28 series excels in its robustness in the applications with 8.22x106 hours of MTBF. The SA50-28 is available in 3.055” x 2.055” x 0.5” package.
