LPD6803 - ETC

LPD6803 3 channel constant-current driver

LPD6803 is a 3 channel constant-current driver and grey-level modulate output , it uses advanced high-voltage CMOS technology, provide 3-way, designed to meet the needs of driving function in the LED lighting system, especially in the dissociation with mutual grey level in the full-colour lighting system.. LPD6803 includes serial shift register and concaten.

Features

◇ 3channel driver output, maxim current per channel is 45mA, LED light voltage can reach 12V. ◇ Output adopt In-Rush online feedback contant-current driver structure, compatible with constant-voltage module, it also can contact outside equipment and transfer to higher voltage or current output driver. ◇ Built-In LDO voltage-stabilizing circuit, voltage range is 3-8v, and have 5V stabilizing voltage output. ◇ Adopt self-add token-ring technology dual shift line, shift clock can reah 24MHz. ◇ Directly input grey-level data, it is transfer to 256 output with reverse-gamma regulator after inside .
