I have this 100W RGB LED, with each color having a max current of ~1A and a voltage of 30-35 Volts (except red which is ~25 V).
Here are my goals:
-I want to drive each color independently with a constant current of 1A at those voltages, as opposed to using a resistor or some other means of driving them.
-I want to be able to control it with the ESP-32, which I believe outputs 3.3V. So I need a circuit to convert it to a 5+V signal or an IC that takes 3.3V input.
-it should be a reasonably efficient circuit where only the LED needs active cooling, not any of the components controlling it
So here is where I need help. Is there an IC that can output those currents and voltages with just, maybe a 40-60V DC power supply and some passive components? Are there some that take 3.3V input? Also, it would need to be through-hole and not SMD because I'm not that good at soldering. I tried looking on mouser but I wasn't really sure if the ICs that were showing up would work, and I didn't know what some of the specifications meant.
Also, all of the constant current boards with those output currents and voltages were $20+ and bulky, and I don't want to spend $60 when there is an easy $5-10 DIY solution.
