LPD6803

Product Description

LPD***3 is designed for LED lighting system design and driving chip, which adopts advanced high voltage CMOS process, with three Lu Heng flow driving and gray scale modulation output, especially for discrete multiple gray color lighting system.

LPD***3 chip includes a serial shift register and cascade drive circuit, the gray data and moderate along into the serial shift register, after the dump pulse width modulation to port 3 output in parallel, serial shift register and gray counter can be made by different clock signal control.Colleague, LPD***3 data and control signals through the internal drive output to the next circuit.

Characteristic.

Three road output driver, each path of maximum current of *5MA, LED lamp voltage up to *2V

The output stage uses IN-RUSH online feedback model constant current driving structure, compatible with constant voltage driving mode, the external device can also be converted to a higher voltage or current of the output drive

The built-in LDO voltage-stabilizing circuit, power supply range of up to **8V, and 5V regulated output

The increment code token technology double shift bus, shift clock up to *5MHZ

Direct data, through the internal SUPER-PWM technology into inverse gamma correction level **6 output, such as the use of the built-in oscillator as a gray clock, support uninterrupted FREE-RUN modulation output, especially for low cost controller application

Data clock signal through the built-in PLL circuit, strong drive is provided to lower chip to cascaded series

High voltage CMOS technology, industrial design, anti-jamming performance of extremely strong resistance

Complies with ROHS environmental protection requirements of SOP*6 / QFN*6 leadless package, but also can provide COB package or DIE bare chip
