MIAMI, 19 July 2012. VPT Inc., a power product designer, announced that the Defense Logistics Agency (DLA) has issued standard microcircuit drawings (SMDs) for VPT's SVGA family of space level, radiation hardened, point of load power converter modules.
With the SVGA series power converters now on official DLA SMDs the components can now be procured quickly, easily and with confidence in their ability to perform in harsh space environments. VPT's SVGA series converters are available in 10A or 15A versions and are suited for use in low Earth orbit (LEO) systems, geosynchronous Earth orbit (GEO) systems, deep space probes, and other space applications. With the two new models being issued SMDs, VPT now offers more than 35 power conversion modules on DLA SMDs designed for operation in space.
The SVGA Series converters function as non-isolated, regulated buck DC-DC converters that step down the voltage at the point of use in a distributed power system. The series features guaranteed TID performance to 100 krads, including ELDRS and operate from 5V input with an adjustable output voltage from 0.8V to 3.4V with 1.5 percent accuracy. The converters comply with many standards, including MIL-PRF-38534 class H and class K, MIL-PRF-38534 element evaluated components, MIL-STD-704A input voltage requirements and other standards.
The radiation hardened SVGA modules are available off-the-shelf in OEM quantities. VPT's space-grade DC-DC converters are ITAR-controlled products that require an export license.
