DD312 is designed for high power constant current LED applications designed to drive. Constant current generating circuit chip embedded, through the outer 
 Linked to resistance to set the value of output current. Through the chip enable terminal can control the output channel switching time, the maximum switching frequency 
 Up to a megahertz (1MHz). Fast response to current output, supports high color depth and high screen refresh rate change application. Built-in open-circuit detection 
 Measurement, thermal shutdown, and overcurrent protection features that make applications greatly enhance the reliability of the system.
