5.12 Minimum on-time (T
ON
,
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 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.
Figure 15.
shows a conversion from
14V to 0.3V at 500KHz with a T
ON
of about 50ns.
The on-time is limited by the turn-on and turn-off times of the MOSFETs.
