StarChips Technology SCT2514 V01_03; Jan/12 4-Output, 8-bit PWM LED Driver with Supply Regulation Feedback Product Description The SCT2514 is a patented SPI+TM interface design for simplicity of backlight local dimming control. It’s an 8#bit constant current sink driver incorporating shift registers and data latches for SPI interface. When the dimming data bytes are written into the SCT2514 in sequence, the patented design initiates a new PWM dimming signal for the output as soon as its luminance data is updated. The maximum current value of all 4 outputs is determined by an external resistor and is adjustable with the OEI signal. Each output also has individual 8#bit PWM dimming control.
