SVFA Series DC-DC Converter
1.0 DESCRIPTION
The SVFA 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 SVFA 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 P. Characterization is performed at both the
component level and at the SVFA hybrid converter level.
The SVFA 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 SVFA.
2. AGND should be connected to GND close to the SVFA. Voltage difference between the AGND and the GND pins greater than 0.3 V may result in regulation error
and/or damage to the SVFA.
3. If not using INH, leave pin 9 open.
4. Rcomp and Ccomp are optional components that can be used to optimize the SVFA transient response.
