Hi
I am using a LP8555 to driver 2 LED bars, LED bar informatin as below picture.
1)String LEDA6 will have longer trace than other 5 strings in port A. So the Vf will be a little higher than others.
What is the max delta value between the 6 strings in one port that LP8555 can handle? Especially considering LEDA6 Vf caused by longer trace.
2)What's the maxium quantity of LEDs that LP8555 can support?
3)For the thermall, I find form the aplication note that Tj=Ta+(Rθja*power).Here power means total power of the LED bar or power of each LED string?
