LM2792 - Current Regulated Switched Capacitor LED Driver

General Description

The LM2792 is a CMOS charge-pump voltage doubler and regulator that provides two regulated current sources.

They are designed to drive two white (or blue) LEDs with matched currents (within ± 0.3%) to produce balanced light sources for display backlights.

LM2792 Current Regulated Switched Capacitor LED Driver with Analog Brightness Control July 2002 LM2792 Current Regulated Switched Capacitor LED Driver with Analog Brightness Control General Description The LM2792 is a CMOS charge-pump voltage doubler and regulator that provides two regulated current sources. They are designed to drive two white (or blue) LEDs with matched currents (within ± 0.3%) to produce balanced light sources for display backlights. The LM2792 accepts an input voltage range from 3.0V to 5.8V and maintain a constant current determined by an external set resistor. The LM2792 delivers up to 34mA of load current to accommodate two high forward voltage (typically white) LEDs. The switching frequency is 900kHz (min.
