DD313 is designed for high-power LED constant current driver designed for applications chip. Built-in three constant-current output channels, can 
 Three external resistors to set output current value, respectively. And three specially designed to enable end to separate and independent control of three output channels 
 Switching time, switching frequency of up to one megahertz (1MHz). Fast response to current output, supports high color depth changes, and high screen brush 
 The application of new rates. Open circuit test-chip, thermal shutdown, and overcurrent protection features that make application of system reliability is further enhanced.
