Reliability Results: Enpirion Power Solutions

Failure in Time (FIT) rate = 2.5

  • @ 55°C, 0.7eV activation energy, 60% confidence, based on HTOL data collected to date (MTBF ~45,000 years)

Because Enpirion PowerSoC products are designed, validated, and qualified as a system, they offer improved system-level reliability versus more discrete power solutions. The following example shows the system-level reliability improvements when using Enpirion PowerSoC products versus discrete solutions.
