BLACKSBURG, Va. – VPT Inc., a HEICO company in Blacksburg, Va., is introducing the VSCPL1210SG point of load DC-DC converter for space applications.

Delivering as much as 10 amps of output current with peak efficiency to 95 percent, the VSCPL1210SG expands VPT's new space product offering is a commercial off-the-shelf (COTS) product line designed for small satellites in low Earth orbits (LEO), and NASA Class D missions.

This series is radiation tested to 42 MeV/mg/cm² with no destructive single-event upset events and tested to 40 krad(Si), guaranteed to 30 krad(Si), for TID in accordance with VPT's in-house radiation hardness assurance (RHA) plan.

Adjustable power output

Operating from a 4.5 to 13.2 volts input and offering an adjustable output from 0.8 to 5.0 volts, the VSCPL1210SG works in temperatures from -55 to 105 degrees Celsius with no power derating.

The proprietary packaging of this space power electronics device enables dual-side heatsinking with low outgassing, while the surface-mount design supports streamlined reflow soldering and simplified board-level integration.

The VSCPL1210SG is manufactured in an ISO9001, J-STD-001, and IPC-amps-610 certified facility and is available for order now. For more information contact VPT online at www.vptpower.com/products/modelseries/vscpl/product/vscpl1210sg.
