Dimming operation
The dimming input disables the switching activity, masking the PWM comparator output.
The inductor current dynamic when dimming input goes high depends on the designed
system response. The best dimming performance is obtained maximizing the bandwidth
and phase margin, when it is possible.
As a general rule, the output capacitor minimization improves the dimming performance.
