Ja det var inte lätt att hitta något om den.
Antar att detta är det från kinesiska översatta du har?
Overview
GW6205 is a dedicated LED lighting products, three-channel constant current LED driver chip, single-wire data transmission mode, the internal integrated digital interface, data latches, LED high voltage driver circuit, chip fixed drive current per channel 18mA. Constant current drive voltage is not stable enough in the environment to achieve the desired display (brightness and color temperature remains constant).
Adjustable realized by controlling the peripheral controller chip 4096 gray, cascade control to achieve a variety of different colorful effects.
Designed to ensure that the output port withstand voltage up to 24 volts, can be connected in series in each of the plurality of LED outputs.
As a result of high-precision constant current drive circuit, and an excellent selection of WAFER processing plants and chip packaging plant to ensure that the chip under different temperature conditions and harsh environment, inter-chip channel to channel, between the film and the film, batch to batch the second between the drive current and good consistency.
GW6205 through the unique technology of anti-static and anti-jamming technology, the chip data transmission is more stable, more reliable.
The chip features
a single output port voltage 24V
any two points on the transmission distance of more than 10 meters without adding any circuit
on the built-in power-on reset
singlet-chip data transfer mode signal shaping circuit
offers three constant current output, fixed output current of 18mA data reception low-speed mode (400Kbps) and speed (800Kbps) modes
lead-free packaging-chip regulator, the need to add a resistor between the power supply and the application process chip VDD pin
PWM control terminal can achieve 4096 gamma adjustment
PWM refresh 1KHz rate for the frame rate no requirements can be achieved linear transfer unlimited cascading accurate output current accuracy: ± 1.5% between channels, ± 3% VDS between the chip can be as low as 0.7V
static capacity greater than 8KV
Chip applications
full color wear Kong Faguang word
LED pixel module full-color
LED full-color light source
RGB lights
