JAJSH28D November 2013 – March 2019 LM3697
PRODUCTION DATA.
The LM3697 features Brightness Register Current Control for simple user-adjustable current control set by writing directly to the appropriate Control Bank Brightness Registers. The current for Control Banks A and B is a function of the full-scale LED current, the 11-bit code in the respective brightness register, and the PWM input duty cycle (if PWM is enabled). The Control A/B brightness must always be written with LSB's first and MSB's last.
