Figure 11. Reducing power during the EN3

6.4

Medium flash mode

To select this operating mode the Enable pins have to be connected as follows:

EN1=1, EN2=0, EN3=0

In medium flash mode the current is set between the Torch and the flash mode levels and can be adjusted

by connecting a resistor between the RMFL pin and the ground:

The medium flash current is then programmed using the following equation:

IMF=10

-5/R

FL • [3000+(13000• RMF/13000+RMF)]. (See Figure 12).
