VPT released its SGRB Series of space qualified dc/dc converters that employ advanced GaN technology. The components are capable of efficiency up to 95%. A fixed-frequency reduced voltage switching topology results in very low input and output noise, making it suitable for use in telecommunication systems.
Specifically designed for applications facing the harsh radiation environments of space, the SGRB Series has been characterized to a Total Ionizing Dose (TID) of 100 krad (Si), including Enhanced Low Dose Rate Sensitivity (ELDRS), and Single Event Effects (SEE) performance to 85 MeV/mg/cm2. The SGRB Series features an integrated EMI filter, 100 V input and 28 V, 400 W output, and is rated for full power operation from -35°C to 85°C. VPT's history of proven space flight heritage ensures long-term performance and reliability. For additional information, peruse the SGRB Series datasheet and visit VPT.
