The SGRB Series of space qualified DC-DC converters (SGRB10028S, SGRB10012S, SGRB10016HCS, and SGRB10020S) is specifically designed for the harsh radiation environment of space applications. Using advanced EPC Space GaN technology, the SGRB is radiation tolerant and achieves very high efficiency. A fixed-frequency reduced voltage switching topology results in very low input and output noise, making it suitable for use in telecommunication systems. VPT’s history of proven space flight heritage ensures long term performance and reliability.
