Dear Mr.Zhou,
I'm sorry for my delayed response and I appreciate your explanation.
>yes, You can use one IFB channel to drive multi LEDS, but there is a problem about the current match may be not very good
>since you use one current sink to drive multi channels. If you don't have very strict demand on the match , it is ok for your application.
Above are your latest comments on this topic.
I understand that we can connect multiple LED strings to one IFB pin
but on this connection the accuracy of controlling current which flows on LED strings will NOT be good.
I don't have further questions on this topic and I'll close this.
I appreciate your cooperation.
Best regards,
Shinsuke Tanaka
