Device description

5.13 Minimum ON-time T
ON(MIN)
The device can manage minimum ON times lower than 100ns. This feature comes from the
control topology as well as from the particular L6730/B overcurrent protection system. In a
voltage mode controller, the current does not have to be sensed to perform regulation and, in
the case of L6730/B, it does not have to be sensed for the overcurrent protection either
because valley current protection can operate during the OFF time. The first advantage related
of this feature is the achievement of extremely low conversion ratios.
Figure 24.
shows a
conversion from 14V to 0.5V at 820kHz with a t
ON
of about 50ns. The ON time is limited by the
MOSFET turn-on and turn-off times.
