LPD6803 datasheet

General Description:

LPD6803 is a 3 channel constant-current driver and grey-level modulate output , it uses advanced

high-voltage CMOS technology, provide 3-way, designed to meet the needs of driving function

in the LED lighting system, especially in the dissociation with mutual grey level in the full-colour

lighting system..

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 output driver.

◇ 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 the requirement of Rohs , also can provide COB

package or DIE.
