▪ 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
