Inductive converters can provide high voltage to drive several WLEDs in series. Charge Pumps typically drive LEDs in
parallel. Selection criteria should be the number of LEDs, which is related to the panel size, and the input voltage range
given by the power source. Efficiency, analog or digital dimming, overvoltage protection and a small solution size are also
important features that should be considered in the selection process.
