AS3694 Datasheet (austriamicrosystems AG) - 12 channel high precision LED driver

AS3694, 12 channel high precision LED driver

The AS3694 is a 12 cannels high precision LED driver with build in PWM generators for building backlight panels in LCD-TV-sets.

3 DCDC Step Up controllers can be used to build the power supplies for red, green and blue LED strings.

External clock and synchronizing inputs allow the synchronization of
