The SA series of DC-DC converters is available in both triple and single outputs. These devices are designed and qualified for the rigors of space including characterization for both Total Ionizing Dose (TID) and Single Event Effects (SEE). Operating at a fixed frequency of 220 kHz, the SA family of parts can be externally synced with other frequency sources.

SA50-120 and SA50-28
Radiation-hardened (rad-hard) DC-DC power converters—the only standard non-hybrid space-grade DC-DC power converters available—utilize surface-mount component construction, allowing flexibility and customization to fit specific applications and requirements. With the SA50 family, qualified to the Mil-Std-461, Mil-Std-883 and Mil-Std-202 standards, you can start with proven Commercially Available-Off-the-Shelf technology and quickly scale up development to reduce your risk and development time.
Benefits of the SA50 Family
- SA50 power converters utilize 28V and 120V input and offer up to 50W of output in a low-profile, small-sized solution
- EMI-compliant and radiation-hardened designs with single and triple outputs are ideal for space station and ORION program platforms
- Units utilize switching regulators that use peak-current-mode controlled single-ended forward converter topology with inherent single-event immunity
- Eight million hours Mean Time Between Failure (MTBF) and up to 87% efficiency, the highest of any standard 28V and 120V input space-grade DC-DC power converter
- Single-output versions additionally offer remote sense, output voltage adjust and parallel connection functions

The current market contains either commercial power converters that are not radiation tolerant, which poses a great risk to the satellite mission life, or expensive radiation-hardened power converters. The LE50 fills the gap between these two by offering a cost-effective radiation-tolerant solution for satellite missions.
