LB1908 Specification Sheet Download
LB1908 is a 3-channel return-to-zero LED constant current driver chip. It supports breakpoint continuation. It has 3 open-drain constant current output terminals, supports 256-level brightness adjustment. PWM refresh rate can reach up to 8K. It provides output channel current dislocation processing to reduce electromagnetic interference and power supply noise. The IC is directly connected to the 12V power supply to reduce the impact of voltage drop; the chip provides dual data input redundant control to ensure signal transmission in the event of damage to the microcontroller. The chip is available in SOP8 package.
