Additional dead time can be added by the addition of a dead time resistor from
Vref to CT. See text on oscillator section for more information.

The sync pulse fed into the clock pin must be at least 3.9 V. RT and CT need
to be set 10% slower than the sync frequency. This circuit is also used in voltage
mode operation for master/slave operation. The clock signal would be coming
from the master which is set at the desired operating frequency, while the slave
is set 10% slower.

The addition of an RC filter will eliminate instability caused by the leading edge spike
on the current waveform. This sense signal can also be used at the ramp input pin for
current mode control. For ramp compensation it is necessary to know the gain of the
current feedback loop. If a transformer is used, the gain can be calculated by:
