资 源 简 介

The LM3432/LM3432B are 6-channel high voltage currentregulators which provide a simple soluTIon for LED backlightapplicaTIons. These devices incorporate six individual currentregulator channels to give accurate driving current for eachLED string. The string-to-string tolerance is kept within ±2.0%.AddiTIonally, the Dynamic Headroom Control output can communicatewith a LM3430 boost regulator to adjust the LEDsupply voltage to the lowest level needed to keep the stringcurrent in regulaTIon, yielding optimal overall system efficiency.
