Minimum on-time (TON, MIN)
The device can manage minimum on-times lower than 100 ns. This feature comes down
from the control topology and from the particular over-current-protection system of the
L6732. In fact, in a voltage mode controller the current has not to be sensed to perform the
regulation and, in the case of L6732, neither for the over-current protection, given that
during the off-time the valley-current-protection can operate in every case. The first
advantage related to this feature is the possibility to realize extremely low conversion ratios.
The on-time is limited by the turn-on and turn-off times of the MOSFETs.
