General Description:
LPD6803 is a 3 channel constant-current driver and grey-level modulate output , ituses advanced high-voltage CMOS technology, provide 3-way, designed to meet the needs of driving function in the LEDlighting system, especially in the dissociation with mutual grey level in the full-colour lightingsystem..
LPD6803 includes serial shift register and concatenation driver circuit, grey level data shift into serial shift register in the clock, and transfer saving , it transfer to interface 3 after pulse-width modulate ,then output, serial shift register and grey-level counter can be controlled by different clock signal. In the meantime, LPD6803 driver data signal and control signal , and output next circuit.

FEATUREs:
◇ 3channel driver output, maxim current per channel is 45mA, LED light voltage can reach 12V.
◇ Output adopt In-Rush online feedback contant-current driver structure, compatible with
   constant-voltage module, it also can contact outside equipment and transfer to higher voltage
   or current outputdriver.
◇ Built-In LDO voltage-stabilizing circuit, voltage range is 3-8v, and have 5V stabilizing voltage output.
◇ Adopt self-add token-ring technology dual shift line, shift clock can reah 24MHz.
◇ Directly input grey-level data, it is transfer to 256 output with reverse-gamma
   regulator after inside SUPER-PWM technology, e.g, adopt built-in oscialator as grey
   level clock, it support FREE-RUN module output, especially can be used in low-cost
   controller.
◇ Data clock signal is drived strongly to next chip to enhance level after built-in phase lock circuit.
◇ High-voltage CMOS technology, industrial design, with extra-good interference immunity
◇ With SOP16/QFN16 Pb-Free package, meet therequirement of Rohs , also can provide COB package orDIE.
