VPT introduces 120 V SGRB DC-DC converter featuring GaN technology

10 May 2022

VPT Inc., a HEICO company, announced the availability of its 120 V SGRB12028S DC-DC converter. Using advanced EPC space gallium nitride (GaN) technology, the SGRB12028S is capable of very high efficiency, up to 95%, and is radiation hardened. A fixed-frequency reduced voltage switching topology results in very low input and output noise, making it suitable for use in a variety of high-power space payload or bus applications.

Specifically designed for applications facing the harsh radiation environments of space, the SGRB series of space rated DC-DC converters has been characterized to total ionizing dose (TID) of 100 krad(Si), including low dose rate (LDR), and single event effects (SEE) performance to 85 MeV/mg/cm2. The SGRB series Source: VPT Inc.Source: VPT Inc.features an integrated EMI filter, 120 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.

“Expanding the SGRB product family with offerings that include a 120 V bus solution continues to allow VPT to be an industry leader in high efficiency, space application, DC-DC converters,” stated VPT engineering manager, John Evans. “The SGRB product is a great building block to both 100 V and 120 V space power systems.”

The availability of the SGRB series is subject to all applicable U.S. export license restrictions and regulations.
