SVSA2800S SERIES

SPACE QUALIFIED HYBRID DC-DC CONVERTERS

SVSA Series DC-DC Converter

Models Available

Input: 15 V to 50 V continuous, 80 V transient

6 W, single output of 3.3 V, 5 V, 5.2 V, 12 V, 15 V

Qualified to MIL-PRF-38534 Class H and Class K

1.0 DESCRIPTION

The SVSA Series of space qualified 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 SVSA 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 SVSA Series hybrid converter level.

The SVSA Series of 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.
