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 other lighting features

keypad LEDs, for example). Brightness of the two

groups can be adjusted independently with pulseAPPLICATIONS

width modulated (PWM) digital signals.

The LM2796 works off an extended Li-Ion input voltage range (2.7V to 5.5V). Voltage boost is

achieved with a high-efficiency 3/2×-gain charge

pump.

The LM2796 is available in TI’s chip-scale 18-bump

DSBGA package.
