Backlight Drivers
LP39542 has 2 independent backlight drivers. Both drivers
are regulated constant current sinks. LED current for both
LED banks (WLED1…4 and WLED5…6) are controlled by 8-
bit current mode DACs with 0.1 mA step.
WLED1…4 and WLED5…6 can be also controlled with one
DAC for better matching allowing the use of larger displays
having up to 6 white LEDs in parallel.
Display configuration is controlled with DISPL bit as shown in
the following table.
DISPL
