| Single Line Drive Chip for Lighting  ZQ1111/1112

ZQ1111/1112 is a single line transmitting chip specially designed for LED drive and it adopts advanced CMOS process, especially suited to multi pieces of cross board serial-parallel. ZQ1111/1112 use single line method to transmit signal, recoding data needed by serial-parallel and then send out. This avoids signal discrepancy caused by multi serial-parallel. In theory, it has 1024 pieces of serial-parallel capacity and ensures data can be updated synchronously. ZQ1111/1112 have 3 channels PWM controlling signal output. Each channel has 4096 brightness depth which adopts uniformity technology to make grey level to be plain and elegant. ZQ1111/1112 use SOP8 packet. integral clock is put inside without other surrounding parts. By this the size of printed circuit board is reduced effectively.
