BLACKSBURG, Va., April 1, 2008 /PRNewswire/ -- VPT, Inc., the
innovative leader in providing power handling products, today introduced
more than 50 DC-DC converter modules specifically designed and manufactured
for space applications. Grouped into four product families, these new space
DC-DC converters deliver up to 120 watts of output power, operate reliably
through harsh radiation environments, and are available for fast delivery
at reasonable cost.
"VPT is the first to provide DC-DC power conversion products with a
guaranteed radiation tolerance through long-term exposure to low dose
radiation, the most typical type that affects the success of the mission,"
explained Michael J. Bosmann, Senior Vice President of Sales and Marketing
for VPT. "Years ago we were focused on a total dose of 100krad or more, but
over time the industry has learned that continual low dose radiation is
much more of a concern and typical of that encountered during the
application. Our new product line satisfies today's updated reliability
requirements for space including the new radiation requirements, small size
and light weight mandates, stringent requirements of 100% reliable
operation through a wide range of space flight conditions, and fast product
Built for Today's Space Requirements
VPT packages its "S" space series of DC-DC converters in miniature,
hermetic, metal cases for reliable power delivery through the extreme
temperature, shock, vibration, and radiation environments of space travel.
Specific features of the new SVSA, SVHF, SVTR and SVFL product families
-- Six to 120 watts of output power in standard single and dual output
-- Characterization and guarantee to 30krads (Si) per VPT's RHA plan
specified per MIL-PRF-38534, Appendix G, Level P with 2x margin*
-- Characterization and testing for TID (total ionizing dose) at HDR (high
dose rate) and LDR (enhanced low dose rate sensitivity -- ELDRS) per
VPT's RHA plan*
-- MIL-PRF-38534 Class H element evaluated components standard
-- Components selected from database of recommended RH devices
-- Designed and manufactured in a facility certified to MIL-STD-883 and
MIL-PRF-38534 Class H (military) and K (space) and qualified to
-- Characterization and testing performed at the critical semiconductor
component piece-part level (radiation lot acceptance test -- RLAT) from
traceable semiconductor lots
-- Characterization and testing also performed on the converters produced
from the same traceable semiconductor lots evaluated during RLAT
-- No pure tin -- guaranteed
-- Fault tolerant design with radiation immune magnetic isolation
technology -- no optoisolators
-- Wide case temperature operation of -55�C to +125�C with full
performance over entire temperature range
* VPT's certified radiation program per MIL-PRF-38534, appendix G, is
currently under review by the Defense Supply Center Columbus (DSCC).
