LM2793 - Low Noise White LED Driver
The LM2793 is a highly efficient, semi-regulated 1.5x CMOS charge pump that provides dual constant current outputs.
The LM2793 has an input voltage range of 2.7V to 5.5V.
To control LED brightness, the amount of current driven to the current-mode outputs can be adjusted with an analog voltage and/or
