DMX512 differential parallel protocol LED constant current driver chip, strong signal anti-interference ability, high port refresh rate, high glow effect, more closely match the human eye visual perception. Simple and convenient maintenance, the abnormality of a chip does not affect the normal work of other chips. Chip withstand voltage up to 30V, the maximum current 200mA high-precision constant current output channel, can short-circuit multiple groups of constant current output interface to expand the current drive capability, and support PWM reverse polarity frequency reduction output function, external triode, MOS tube current expansion drive. Mainly used in building decoration and stage lighting effects of LED lighting system.
