FEATURES  
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.

3.0V to 5.8V Input Voltage  
Up to 34mA Output Current  
Soft Start Limits Inrush Current  
Analog Brightness Control  
Separate Shutdown Input  
The LM2792 delivers up to 34mA of load current to  
accommodate two high forward voltage (typically  
white) LEDs. The switching frequency is 900kHz  
(min.) to keep the conducted noise spectrum away  
from sensitive frequencies within portable RF  
devices.  
Very Small Solution Size and No Inductor  
1.4mA Typical Operating Current  
1µA (max.) Shutdown Current  
900kHz Switching Frequency (min.)  
Linear Regulation Generates Predictable Noise  
Spectrum  
The LM2792 offers full off to maximum current control  
through the BRGT pin. The output current linearly  
tracks the BRGT pin voltage. The LM2792 is  
available in active high or low shutdown versions.  
The shutdown pin reduces the operating current to  
1µA (max.). The LM2792 is available in a 10 pin  
WSON CSP package.
