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 the LCD backlight with the TV picture.

include thermal shutdown as well as open and short LED detection. All circuit parameters are programmable via I2C or SPI interface.
Output slew rate limited to reduce EMI Current programmable with external resistor 12 independent PWM generators with 12 bit resolution H-Sync, F-Sync inputs to synchronize with TVset Three independent power feedback for R-, G-, B-supply regulation Build in 5V shunt regulator I2C or SPI interf.
