During Mixed Decay mode and Fast Decay mode, if the setting current value < output current at RNF:
current monitoring point, the Charge mode at the next chopping cycle will disappear and the pattern will
change to Slow Fast Mode (Slow → Fast occurs at MDT). (In reality, a charge is applied momentarily to
confirm the current.)
Note: These figures are intended for illustrative purposes only. If designed more realistically, they would show
transient response curves.

Since the current's rate of decay is fast, its compliance
with the setting current value is also fast.

Since the current's rate of decay is slow, its
compliance with the setting current value takes a
long time (or may not follow at all).
