Tool/software:
Hi,
I have some follow up questions in relation to this thread.
Texas Instruments (Sarah Koch) has stated "the range of the [TPS50601A-SP] spec includes variation from temp, load, supply voltage, radiation and group C aging." Group C tests are performed for 1000 hours at 125°C. How can the datasheet variations be applied to products with longer lifetimes, e.g., 5, 10, 15, or 20 years? If an Arrhenius extrapolation is appropriate, what is the shape of the graph of variation versus time, e.g., linear, logarithmic, cube root, etc.? Also, is the activation energy to be used in such an Arrhenius extrapolation known?
What statistics would you ascribe to the datasheet parameter value ranges, e.g., what is the probability density function shape and standard deviation?
