General Description
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.
Key Features
- 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.
