BLACKSBURG, Va. – VPT Inc. in Blacksburg, Va., is introducing the SVPL series space-qualified point-of-load DC-DC converter power supplies for radiation-hardened space applications facing harsh radiation environments while requiring low voltages and tight regulation for high-performance processors.

These power electronics devices cover an input voltage range of 3.1 to 13.2 volts and are available in 6-, 9-, and 12-amp output surface-mount options.

The SVPL series use the Renesas ISL7000x family of rad-hard synchronous buck regulators to provide high power density, fast transient response, and as much as 94 percent efficiency.

The ISL7000x bare-die integrated circuits (ICs) are characterized for total ionizing dose (TID) of 100 kilorads, including enhanced low dose rate sensitivity (ELDRS), and they are immune to destructive single event effects (SEE) with linear energy transfer (LET) of 86.4 MeV-cm2/mg.

The SVPL series of converters are characterized for TID of 100 kilorads, including ELDRS, and SEE performance to 85 MeV-cm2/mg, per VPT's DLA-approved radiation hardness assurance (RHA) plan.

Additional features include high power density, output enable control, low output noise, overcurrent protection, and external synchronization to other converters or system clocks. Full power operation of the SVPL series is rated for -55 to 125 degrees Celsius.
