SVGA0515SG Point of Load DC-DC Converter
As the world’s first RAD HARD point of load converter, VPT’s SVGA Series is mission proven in systems launching for LEO, MEO, GEO, and deep space missions. Qualified to MIL-PRF-38534 Class K on DLA SMDs, these off-the-shelf units help you get your system off the ground fast. View VPT’s space program heritage.
The SVGA Series is an extremely efficient point of load DC-DC converter for stepping down voltage at the point of use. It is ready for rugged duty with characterization to 100krad (Si) total dose radiation under VPT’s certified radiation program per MIL-PRF-38534, Appendix G.
Operating at a nominal frequency of 250 kHz, these regulated non-isolated converters are optimized for low voltage point of load applications with high efficiency synchronous rectification and fast transient response. The SVGA point-of-load converters are designed and manufactured in a facility qualified to ISO9001 and certified to MIL-PRF-38534 Class H and Class K and MIL-STD-883.
Combine our extensive family of DC-DC converters for space with these point of load converters for space to create a light weight, extremely efficient, space-ready power system.
