Figure 13, the MP2636 continuously compares
the high-side FET sense current with comp level,
if the sense current doesn’t reach the comp level
within the original switching period, the next clock
will be delayed until the sense current reaches
the comp level. As a result the duty cycle is able
to be extended as large as possible.
