SVGA Series DC-DC Converter
1.0 DESCRIPTION
The SVGA Series of space qualified point of load DC-DC
converters is specifically designed for the harsh radiation
environment of space applications. Performance is guaranteed
through the use of hardened semiconductor components,
radiation lot acceptance testing (RLAT) of non-hardened
components, and analysis. The SVGA Series has been
characterized for Total Ionizing Dose (TID) performance
including Enhanced Low Dose Rate Sensitivity (ELDRS) and for
Single Event Effects (SEE) according to VPT’s DLA-approved
Radiation Hardness Assurance (RHA) plan per MIL-PRF-38534,
Appendix G, Level R. Characterization is performed at both the
component level and at the SVGA hybrid converter level.
The SVGA Series of point of load DC-DC converters is radiation
tolerant and suited for use in low Earth orbit (LEO), medium
Earth orbit (MEO), geostationary orbit (GEO), deep space, and
launch vehicle programs.

2.0 DIAGRAMS
2.1 BLOCK DIAGRAM
2.2 CONNECTION DIAGRAM
1. Rtrim should be connected directly across pins 11 and 12 as close as possible to the SVGA.
2. AGND should be connected to GND close to the SVGA. Voltage difference between the AGND and the GND pins greater than 0.3 V may result in regulation error
and/or damage to the SVGA.
3. If not using INH, leave pin 9 open.
4. Rcomp and Ccomp are optional components that can be used to optimize the SVGA transient response.
