Minimum on-time (TON, MIN)
The device can manage minimum on-times lower than 100ns. This feature comes down from
the control topology and from the particular over-current-protection system of the L6732C. In
fact, in a voltage mode controller the current has not to be sensed to perform the regulation
and, in the case of L6732C, 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. Figure 12. shows a
conversion from 14V to 0.3V at 500KHz with a TON of about 50ns.
The on-time is limited by the turn-on and turn-off times of the MOSFETs.
