VSC5-2800S DC-DC Converter
The VSC5-2800S Series is a commercial off the shelf DC-DC converter designed for the ‘NewSpace’ market. Performance is guaranteed through the use of radiation lot acceptance tested (RLAT) components. Our proprietary packaging creates a dual side heatsinking option with very low outgassing.
Radiation tested to 42 MeV/mg/cm2 and guaranteed to 30 MeV/mg/cm2 for SEE and tested to 40 krad(Si) and guaranteed to 30 krad(Si) for TID in accordance with VPT’s inhouse radiation hardness assurance (RHA) plan.
The VSC5-2800S Series are designed for smaller satellites in low Earth orbits (LEO), launch vehicles, and NASA Class D missions where the balance of cost and guaranteed performance is critical.
Features:
- Output Voltage +3.3 V, +5 V, +12 V, +15 V
- Wide input voltage range: 15 V to 50 V plus 80 V transient
- Continuous operation over full military temperature range of
-55 °C to +100 °C with no power derating - Very low output noise
- No use of optoisolators
- Undervoltage lockout
- Current limit protection / short circuit protection
Space-Level Characterizations:
- Guaranteed TID performance to 30 krad(Si) including LDR
- SEE performance to 30 MeV/mg/cm2. Transients are fully analyzed for cross-section and magnitude
Compliances and Certifications:
- Manufactured in a facility certified to ISO9001, J-STD-001, and IPC-A-610
