Hi Guys,
Up until now i've been using a 12v buck type led driver to drive and led unit with 3 led's wired in parallel. It gives my LED unit 3.2v fixed voltage and a constant current of 300mA. I cannot find any buck type drivers that give lower than 300mA and is a 12V DC input. So i'm wondering if anyone knows how I can build a simple circuit just to give me a fixed output of 3.2v and a fixed current of 75mA. I dont need it to be complex or adjust depending on the if more led's are added or if it's change from parallel to series as this will not be the case. So just want to deliver the exact specification this led unit needs
Thanks
