General Description
The LM2796 is a charge-pump based white-LED driver that is ideal for mobile phone display backlighting.
It can drive up to 7 LEDs in parallel with up to 20mA through each LED.
Regulated internal current sources deliver excellent current and brightness matching in all LEDs.
The LED-driver current sources are split into two independently controlled groups.
The primary group (4 LEDs) can be used to backlight the main phone display.
The second group (3 LEDs) can be used to backlight a secondary display or to provide ot...
