Hello everyone, I am in need of some help operating the following component: http://www.vishay.com/docs/83615/il211at.pdf The 360V and 5V inputs are fixed, as well as the need for 2.5V at the indicated location. The trouble I'm having is really understanding how the chip works as well as how to have it operating in, I believe it's called, linear mode? Essentially, I want the 2.5V to change as a function of the 360V changing as well. My current understanding is that the current going through the diode is halved (because of the CTR) and then that current is represented by the transistor behaving as a sort of resistor, which causes a sort of voltage divider behavior. Thanks for any help!
