LPD8803 LPD8806 IC for LED Strip chip Components
This pixel protocol was designed by Qiancai Electronics in China. Very similar to its previous version, LPD8806 LPD8803 provides 8 bits of data, for better color resolution and smoother dimming curves. It also uses improved optics to achieve a higher PWM rate. The control circuit comes in a SOP16 package, allowing for more flexibility with LED choice.
LPD8803/LPD8806 as a new generation of driver chips are designed for the LED lighting system, which uses industrial grade CMOS process, providing multi-channel constant
current driver and grayscale modulation output, it is programable, LPD8803 and LPD8806 output 3chanhel and 6 channel respectively,signal particularly suitable for discrete multigray full-color lighting system.
