Part Number: LP5569

As shown in figure, RGB Led and LP5569 connection is given to run this circuit 3.3v is enough ? if it is enough, 3.3v connection is suitable for LP5569 electrical Characteristic.?

Hi Mustafa,

It depends on the forward voltage of your LEDs. Generally VLED should be higher than Vsat (LP5569 is 0.1V) plus Vf (forward voltage at the current you set) and I think 3.3V should be enough for common LEDs. 3.3v is OK for LP5569 power supply.
