Operation Modes
LM3520 has two operating modes;
Figure 2
shows main
display in PWM current mode operation, the appropriate
selection of R
FB
resistor in series with four white LEDs set
the output current driving the main display.
Figure 3
shows
Sub display in PFM mode, the appropriate selection of
R
and R
resistors set the output voltage driving the
OLED subdisplay.
