LM3432 6-Channel Current Regulator

LM3432 Description

LM3432/LM3432B 6-Channel Current Regulator for LED Backlight Application www.DataSheet4U.com May 22, 2008 LM3432/LM3432B 6-Channel Current Regulato.
The LM3432/LM3432B are 6-channel high voltage current regulators which provide a simple solution for LED backlight applications.

LM3432 Features

* Dynamic Headroom Control (DHC) output to maximize efficiency when used in conjunction with National Semiconductor's LM3430 Boost Controller for LED Backlighting Current sinking adjustable up to 40mA in each string Fast current switching slew rate, tr = 60ns typical Wide dimming ratio, up to 40

LM3432 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 vol
