Hey Guys,
Need help with a little project that I'm working on.
I need to make a DC DC buck converter for an input of 24v-160v and I need it to output 5v at 200ma (Maybe 500ma)
I've been trying to model a circuit after Roman Black. He has a website with some
2-transistor Black Regulator
Anyone have any links or quick circuits they can draw up to make such a thing happen? Is it even possible to have such a wide range of input voltage?
I've also read about people using high voltage P Fets in conjunction with a regular switcher. The idea is you use the switcher to switch the P fet gate while powering up the switcher with a power resistor or zener dropped down from your main voltage.
I'm not exactly sure how that works.
Any support would be greatly appreciated.
