Radiation-hardened DC-DC converter for orbital and deep-space applications introduced by VPT
BLACKSBURG, Va., 10 May 2012. VPT Inc. in Blacksburg, Va., is introducing the radiation-hardened SVGA0515 series point of load DC-DC converter for use in the extreme environment of space. VPT experts have qualified the SVGA0515 to MIL-PRF-38534 Class H and Class K.
The rad-hard SVGA series functions as a non-isolated, regulated buck converter that steps down the voltage at the point of use in distributed power systems headed for low-, medium-, and geosynchronous Earth orbits, as well as for deep-space missions.
The power electronics device delivers as much as 50 Watts of output power, is radiation hardened to 100 kilorads (Si) including enhanced low dose rate sensitivity (ELDRS), and is characterized to SEE of 85 MeV-cm2/mg.
VPT guarantees the performance of the SVGA0515S in space systems by design through worst-case analysis, use of radiation-hardened components, and radiation lot acceptance testing (RLAT) of semiconductor components. The SVGA comes in hermetically sealed metal cases, company officials say.
