Figure 13. Dimming signal
For example, assuming a 1 kHz dimming frequency the maximum dimming depth is 5% or,
given a 2% dimming depth, it follows a 200 Hz maximum f
The LED2000 dimming performance is strictly dependent on the system small signal
response. As a consequence, an optimized compensation (good phase margin and
bandwidth maximized) and minimized C
