16-Channel White LED Controller for LCD Backlight
1 Description
The AS3824 is a 16 channel high precision LED controller for use in LCD-backlight panels. Dynamic power feedback controls the external power supply to guarantee best efficiency. One high accurate global 10 bit DAC can be used to set the LED current as well as each channel has its own additional 8 bit DAC to boost the dynamic range of LED Backlight systems.
Each channel is equipped with an independent PWM generator which can also be synchronized to an external synchronization signal (VSYNC).
A fast mode supports minimum PWM duty cycle operation which helps to further reduce the energy consumption of modern LED Backlight...
