▪ Supports all LED backlight topologies
▪ No limit of VLED or ILED, device is not
exposed to high voltage/high current
▪ Optimum power savings through local dimming
▪ 16 fully flexible 12 bit PWM generators (period,
high time, delay, reverse)
▪ One global highly accurate 10 bit DAC which
sets the LED current (±0.5% accuracy)
▪ High dynamic range boost function
▪ 16 independent 8 bit DACs can be used to
boost/decrease LED current within certain
frames
▪ Global dimming mode option
▪ AS3824E/E1 are pre-programmed as external
PWM mode (DPWM mode), VSYNC pin is used as
PWM input. AS3824A/A1 are pre-programmed
as SPI mode
▪ VSYNC and HSYNC inputs, as well as
integrated digital PLL for synchronization with
TV frame
▪ Lowest BOM
▪ Due to 2 pin concept of the output channel: no
HV protection, no cascade FETs
▪ Feedback function is compatible to every DCDC architecture and configurable via SPI
▪ Short/OPEN LED detection, temperature
shutdown, register lock/unlock, SPI transfer
