VPT’s SV Series of DC-DC converters are mission proven in systems launching for LEO, MEO, GEO, and deep space missions. Qualified to MIL-PRF-38534 Class K on DLA SMDs, these off-the-shelf units help you get your system off the ground fast. View VPT’s space program heritage.
With no stacked capacitors, the SVFL family of DC-DC converters utilize well controlled under-voltage lockout circuitry to eliminate slow start-up problems. Current sharing enables parallel operation of up to five units for 5x power output.
- Dual outputs of ±5V, ±12V, and ±15V
- Wide 16V to 40V input range with 50V transient
- Up to 120W output power
- Parallel operation with current sharing up to five units
- Fault tolerant design with radiation immune magnetic isolation technology – no optoisolators
- Extremely low profile (.400 inches) and light weight (86g) fully hermetic packaging
- Wide case temperature operation of -55° C to +125° C with no power derating
- 500Vdc input/output isolation
- Fixed switching frequency
- Characterized and guaranteed to 30krads (Si) per VPTs RHA plan specified per MIL-PRF-38534, Appendix G, Level P with 2x margin
- Characterized and tested for TID (total ionizing dose) at HDR (high dose rate) and LDR (low dose rate ELDRS) per VPTs RHA plan
- SEE characterized for no destructive events up to LET = 44 MeV-cm2/mg including SEB, SEL, SEGR, and SEFI. No dropouts, shutdowns, latch up or burn out. Up to 85 MeV-cm2/mg also available.
- Characterization and testing is performed at the critical semiconductor component piece-part level (RLAT) from traceable semiconductor lots
- Characterization and testing also performed on the SVFL Series hybrid converter produced from the same traceable semiconductor lots evaluated during RLAT
