LM2796 - Dual-Display White LED Driver

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 sou

* (keypad LEDs, for example). Brightness of the two groups can be adjusted independently with pulsewidth 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 highefficiency 3/2x-gain charge pump. The LM2796 is ava
