Function

1 DIN

Serial data input, built-in voltage pull-

up

Grey-level regulate mode: GMODE=1,adapt

2 GMODE

line modulate,GMODE=0,adapt re-Gama 256

grade non-line regulate,built-in voltage

pull-up

Control output polarity: OMODE=1, output

3 OMODE

is in-constant current/voltage drive

mode,CMODE=0, output is out drive

mode,voltage built-in pull-up

choose inside grey clock GCLK, CMODE=0,

13 CMODE

GCLK=DCLK, CMODE=1, GCLK= inside

oscillator output, built-in pull-up

4 DCLK

Serial data clock input, built-in pull-up

5,7,11 OUT1,OUT2,OUT3

3-way driver output

6,8,10 FB1,FB2,FB3

Feedback input in constant current state

15 DOUT

Serial data output, after inside strongly

drive

12 DCLK0

Serial clock output, after inside pll and

strongly drive

16 VCC

LDO power, range is 4.5v---8v

when VCC>5V, 5V stable voltage output,

14 VOUT

when VCC<5V, VOUT=VCC, can be used as

inside working voltage, suggest outside

contact a 0.01uF----0.1uF capacity

9 GND

Ground
