VPT Introduces SGRB DC-DC Converter Series Featuring GaN-Based Technology

Washington, May 6, 2019 /PRNewswire/ -- VPT, Inc., a HEICO company (NYSE:HEI.A) (NYSE:HEI), today released its SGRB Series of space qualified DC-DC converters at the Satellite 2019 Show. 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.

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's history of proven space flight heritage ensures long-term performance and reliability.

"We developed these products to provide a solution that dramatically increases the power supply efficiency," said Jeremy Ferrell, VPT's Director of Engineering. "This, in turn, greatly reduces the system size, weight, and cost. The SGRB product uses GaN technology that allows us to increase the efficiency beyond the traditional radiation hardened silicon offering."

"VPT is pleased to announce our first GaN based, 100V input DC-DC converters designed specifically for space applications," Malcolm Campbell, VPT's Executive Director of International Sales and Marketing said. "The SGRB product specifications are particularly well suited for space-borne telecommunication applications where high efficiency, low noise, and radiation tolerance are critical to mission success. Further, we see the design topology of the SGRB as the beginning of an exciting family of future models based on GaN technology."

VPT is reviewing specific customer requests for custom orders of the SGRB Series. Additional information on the SGRB Series of DC-DC converters and specific product data can be found at
