1.0 DESCRIPTION
1.2 SPACE LEVEL CHARACTERIZATIONS
The SVPL Series of space qualified point-of-load DC-DC
converters is specifically designed for the harsh radiation
environment of space applications. Performance is guaranteed
through the use of hardened semiconductor components and
analysis. The SVPL Series has been characterized for Total
Ionizing Dose (TID) performance including Enhanced Low Dose
Rate Sensitivity (ELDRS) and for Single Event Effects (SEE) per
VPT’s DLA-approved Radiation Hardness Assurance (RHA) plan
per MIL-PRF-38534, Appendix G, Level R.
• Total Ionizing Dose Performance
• High Dose Rate [50-300 rad(Si)/s] ≥ 100 krad(Si)
• Low Dose Rate [<10 mrad(Si)/s] ≥ 100 krad(Si)
• Single Event Effects Performance
• SEL, SEB, and SEGR LETTH ≥ 85 MeV-cm2/mg
• SEFI Threshold LETTH ≥ 58 MeV-cm2/mg
• SEFI X-section (LETEFF = 85 MeV-cm2/mg) ≤ 6.59x10-7 cm2
• SET fully characterized for cross section and magnitude
• Operation from -55 °C to +125 °C
• Worst-case analysis, stress, radiation, reliability reports available
The SVPL3R312SG is based on the Intersil ISL70002SEH
radiation-hardened monolithic buck regulator. It is designed to
operate from a nominal 3.3 V or 5 V bus. The SVPL3R312SG
supplies low voltages at 12 A with high efficiency and fast
transient response, making it an ideal choice to supply point-of-
load applications such as high performance space processors.
