AS3693AA Product Brief www.DataSheet4U.com 1 General Description ƒ Product Brief Output slew rate limited to reduce EMI AS3693A 16 channel high precision LED driver for LCD backlight The AS3693A is a 16 cannels high precision LED driver with build in PWM generators for building backlight panels in LCD-TV-sets. 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 independent PWM generators with programmable delay, period and duty cycle. Three free configurable dynamic power feedback circuits make the device usable for white LED as well as RGB backlights. Build in safety features include thermal shutdown as well as open and short LED detection.
