If for any particular reason, there is a need for a
frequency variation linked to an event appearance (instead
of abruptly stopping pulses), then the FB pin lends itself
very well to the addition of other sweeping loops. Several
diodes can easily be used perform the job in case of reaction
to a fault event or to regulate on the output current (CC
operation). Figure 39 shows how to do it.

Dead--time Control
Dead-- time control is an absolute necessity when the
half-- bridge configuration comes to play. The dead-- time
technique consists in inserting a period during which both
high and low side switches are off. Of course, the
dead-- time amount differs depending on the switching

frequency, hence the ability to adjust it on this controller.
The option ranges between 100 ns and 2 m s. The dead-- time
is actually made by controlling the oscillator discharge
current. Figure 40 portrays a simplified VCO circuit based
on Figure 31.
