is forward current limit.
Note 4: Turn-on time and turn-off time are defined as the difference in the time between when the output crosses 10% and 90%
of the final output voltage.
Note 5: Blanking time and retry time are generated by the same oscillator. Therefore, the ratio of
is a constant value of 32. See Figures 2 and 3.
