Figure 13 shows the lower limit for the on time t
ON
for having a good PWM current regulation capacity. It has to
be said that t
ON
is always bigger than t
ON(MIN)
because the device imposes this condition, but it can be smaller
than t
RCRISE
- t
DT
. In this last case the device continues to work but the off time t
OFF
is not more constant.
So, small C
OFF
value gives more flexibility for the applications (allows smaller on time and, therefore, higher
switching frequency), but, the smaller is the value for C
OFF
, the more influential will be the noises on the circuit
performance.
