EUP2796 - Dual-Display White LED Driver

Description

The EUP2796 is a charge-pump based white-LED driver that is ideal for mobile phone display backlighting.

It can drive up to 6 LEDs in parallel with up to 20mA through each LED.

Regulated internal current sources deliver excellent current and brightness matching in all LEDs.

Features

  • (keypad LEDs, for example). Brightness of the two groups can be adjusted independently with pulse-width modulated (PWM ) digital signals. The EUP2796 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 EUP2796 is available in a 16-pin TQFN package.

EUP2796 Dual-Display White LED Driver with 3/2X Switched Capacitor Boost DESCRIPTION The EUP2796 is a charge-pump based white-LED driver that is ideal for mobile phone display backlighting. It can drive up to 6 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 www.DataSheet4U.com the main phone display. The second group (2 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 pulse-width modulated (PWM ) digital signals.
