10 Summary

The purpose of this study was to characterize the effect of heavy-ion irradiation on the single-event effect (SEE) performance of the TPS7H4003-SEP synchronous step-down POL converter. Heavy-ions with LETEFF = 48.2 MeV·cm2/mg were used for the SEE characterization campaign. Flux of 105 ions/cm2·s and fluences of 1 × 107 ions/cm2 per run were used for the characterization. The SEE results demonstrated that the TPS7H4003-SEP POL is free of destructive SEB events and SEL-free up to LETEFF = 48.2 MeV·cm2/mg and across the full electrical specifications. Transients at LETEFF = 48.2 MeV·cm2/mg on VOUT and PGOOD are presented and discussed. CREME96-based worst-week event-rate calculations for LEO(ISS) and GEO orbits for the DSEE are presented for reference.
