Simple and efficient 12V to 5V convertor
Fcobcn shared his simple and efficient 12V to 5v converter. It’s based around the TL2575 buck IC, and can output 1 amp of current.
DIY, power supply and tagged buck, switching regulator.
I’m using a TL2575 from ti, wich has a max efficiency of 88%, 1A, works quite well, previously were using a 7805 wich needed heat sinking. There’s apparently no heat coming out from the TL2575 circuit.
