SGRB10012S DC-DC Converter

The SGRB10012 is a space rated DC-DC converter specifically designed for the harsh radiation environments of the most demanding commercial, scientific and military space applications. Using advanced GaN technology, the SGRB is radiation-hardened 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 a variety of high-power space payload or bus applications. VPT’s history of proven space flight heritage ensures long term performance reliability.
