BCR601 hot plug IC with voltage feedback to primary side Functional description
ILED 100% Analog dimming range 3% 0% VMFIO off 3% dim 100% 0.1V 0.2V 3.3 V 5 V
Figure 4 Analog dimming 2.
For analog dimming using Rset and internal MFIO current, the internal pull-down has to be taken into account. For proper dimensioning refer to
Figure 5
