TLC59116FEVM-571: TLC59116FEVM-571

Part Number: TLC59116FEVM-571

Hello,

I just receive the EVM kit and I was looking through the guide !

I was looking on the PCB and notice the C4 and C6 capacitor very big (polarized 15 uF), and the overone, C1,C2,C3,C5 (10 uF). I can't understand why there is this capacitor (especially C4 and C6) ? This is about the different GND layer (one for numeric i2c and one for led analog ?) !

Thanks if you can answer my question !

Regards,

Simon
