AS3693B Datasheet (austriamicrosystems) - 16 Channel high precision LED driver

AS3693B, 16 Channel high precision LED driver

The AS3693B is a 16 channels high precision LED controller with build in PWM generators for driving external FETs in LCD-backlight panels.

External clock and synchronizing inputs allow the synchronization of the LCD backlight with the TV picture.

Local dimming and scan dimming is supported by 16 ind
