The output OVP threshold has been measured in different line/load conditions and the
results are reported in Table 18.
In Figure 41, the same results – normalized with respect to the calculated VOUT_OVP
threshold (7.2 V) – are plotted in a graphic format to show that in any case the actual
threshold is within some percentage of tolerance of the expected value.
