Hi
I'm using the LM27313 boost converter to drive some LEDs. My boss has asked the question. What happens if one of the feedback resistors is not fitted.
If the bottom resistor (between FB and ground) is missing then (I think) the switcher will not switch and the output will track the input voltage (less diode drop)
However what i am not sure about is what happens if the top resistor (between the output voltage and the FB pin) is missing. Theoretically i'd get infinite output voltage but that isn't going to happen.
Any help appreciated.
