The Texas Instruments LM2796 is a charge-pump based white LED driver designed for mobile phone display backlighting. It is capable of driving up to 7 LEDs in parallel, with each LED receiving up to 20mA. The driver utilizes regulated internal current sources to ensure excellent current and brightness matching across all LEDs.
The LED driver current sources are divided into two independently controlled groups. The primary group supports up to 4 LEDs, suitable for main display backlighting, while the secondary group supports up to 3 LEDs for secondary displays or other lighting functions like keypads. Brightness for both groups can be adjusted independently using pulse-width modulated (PWM) digital signals. The LM2796 operates from an extended Li-Ion input voltage range of 2.7V to 5.5V, achieving voltage boost through a high-efficiency 3/2x charge pump.
This device is available in an 18-bump thin DSBGA package measuring 2.1mm x 2.4mm x 0.6mm. It supports PWM brightness control with frequencies ranging from 100Hz to 1kHz. The operating temperature range is from -30°C to 85°C.
