The LM3432/LM3432B are 6-channel high voltage current
regulators which provide a simple solution for LED backlight
applications. These devices incorporate six individual current
regulator channels to give accurate driving current for each
LED string. The string-to-string tolerance is kept within ±2.0%.
Additionally, the Dynamic Headroom Control output can communicate
with a LM3430 boost regulator to adjust the LED
supply voltage to the lowest level needed to keep the string
current in regulation, yielding optimal overall system efficiency.
