As part of a larger project, I have a MAX1701 switching booster in which I want to use a spare opamp to provide a regulated charge to a lipo.
I want the output to be 4.2V and limited to 500mA.
The voltage regulator itself works fine, but I can't get the current limit to work... thing is I have no clue why it doesn't work.
I attached a simplified shematic (there are also a 100uF tant cap on output I forgot in the image)
Anyone can see why it doesn't work ?
