LXY28162, the 16-channel constant current LED Driver, is designed for LED video applications using internal Wise Pulse Width Modulation (W-PWM) control with selectable 16-bit color depth. LXY28162 features 8-bit programmable output current gain to individual channel (pixel correction), 7-bit programmable output current gain to all channels (led display brightness adjustment) and open/short-circuit detection to detect individual LED errors (real time online feedback). LXY28162 saves the 60 Hz images input data in the 8K RAM, then converts into each pixel gray scale of output channel, all output channels can be built with 65536 gray scales and 4800 Hz refresh rate.
LXY28162 has 16 constant-current output channels. Constant output current is invariant to load voltage change. The output current can be preset through an external resistor.Linsn LXY28162 supports static and any scan mode (within 16) led displays. The gray scales and refresh rate is user adjustable. The maximum output constant current is 80mA. The accuracy of output constant current between channels is +1.5%, and between ICs is +3%.
