Hi, I am driving an array of 15 LED in parallel from a 5v source, i intend to drive them using a IRFZ46N, but i need to regulate the current with a very nice precision, what would be the best approach to this issue? I would like that each LED receives it's 20mA, or even 19~~21mA. I created a topic recently and the guys helped solve a problem related to the BJT, but the current isn't constant, that's why i would like help. I intend to supply the voltage at the gate of the mosfet with a 555 and a pull down resistor, the 555 is there for dimming purposes. Thanks in advance.
