10W, Space-Level DC-DC Converters

6/3/2003 10W, Space-Level DC-DC Converters The International Rectifier S-series line of 10W, radiation-hardened, “off-the-shelf” dc-dc converters is available unscreened or screened to Class K per MIL-PRF-38534, simplifying qualification processes and enabling faster project completion compared to custom-designed converters.

Small and light, they’re ideal for low power circuits such as analog and digital control power systems, as well as signal amplifiers and sensors in geo-synchronous (GEO) and low earth orbit (LEO) satellite applications.

The converters feature 28Vdc input, with single or dual output configurations, and operate up to 81% efficiency. They also include various functional and protection features, such as undervoltage lockout, output overvoltage limiter, on/off inhibit, short-circuit and overload protection. Other features include magnetically coupled feedback, with radiation hardness of 100 krads total ionizing dose (TID).
