SVRHF2800D SERIES

SPACE QUALIFIED HYBRID DC-DC CONVERTERS

SVRHF Series DC-DC Converter

Models Available

Input: 18 V to 40 V continuous, 50 V transient

15 W, dual outputs of ±5 V, ±12 V, ±15 V

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

Designed for TOR Compliance

1.0 DESCRIPTION

The SVRHF Series of space qualified DC-DC converters is

specifically designed for the harsh radiation environment of

space applications and is designed in accordance with

Aerospace TOR requirements. Performance is guaranteed

through the use of hardened semiconductor components,

radiation lot acceptance testing (RLAT) of non-hardened

components, and analysis. The SVRHF 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 SVRHF Series hybrid converter level.

The SVRHF Series of DC-DC converters is radiation hardened

and suited for use in low Earth orbit (LEO), medium Earth orbit

(MEO), geostationary orbit (GEO), deep space, and launch

vehicle programs.
