UCC21520: UCC21520 FIT rate for 95% CL

Suresh R

Intellectual 260 points

Part Number: UCC21520

Hi,

The FIT rate given for part UCC21520 is in 60% confidence level. Please let me know how this FIT value can be converted for 95% confidence level (any factor available for conversion?). Or, it would be helpful if FIT value for 95% confidence level is given.

Please suggest how to get FIT value for 95% confidence level.

Thanks & Regards,

Suresh.

Hi Suresh,

Thank you for your question. I work on the applications team in the high power drivers group.

The FIT value for UCC21520 at 95% confidence level is 0.63 when using the values from the DPPM/FIT/MTBF estimator tool.

Feel free to read more about how these values are calculated in section 5 of the Application Report linked below.
