Space Qualified DC-DC Converters Leverage GaN Technology

VPT has released its SGRB Series of space qualified DC-DC converters. Using advanced GaN technology, the SGRB is capable of very high efficiency, up to 95%, as well as radiation tolerance. 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 SGRB DC-DC Converter

Specifically designed for applications facing the harsh radiation environments of space, the SGRB Series has been characterized to 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 is reviewing specific customer requests for custom orders of the SGRB Series.
