Overview
Description
The LM2791 is a CMOS charge-pump voltage doubler and regulator that provides two regulated current sources. It is designed to drive two white or blue LEDs with matched currents (within ±0.3%) for balanced light sources in display backlights. The LM2791 accepts an input voltage range from 3V to 5.8V and maintains a constant current determined by an external set resistor.

Features
Output matching of ±0.3%
Drives up to two LEDs
3V to 5.5V input voltage
Up to 36mA output current
Soft start limits inrush current
Analog brightness control
Separate shutdown input
Very small solution size - no inductor
0.7mA typical operating current
1μA (max.) shutdown current
450kHz switching frequency (min.)
Linear regulation generates predictable noise spectrum
LLP-10 package: 3mm X 3mm X 0.8mm

Applications
White LED display backlights
White LED keypad backlights
1-Cell Li-Ion battery-operated equipment including PDAs, hand-held PCs, cellular phones
Flat panel displays
