CUrrent Sesning Issue
Hi,
I am working on Peak Current Mode DC-DC converter.I am using OPAMP based current sesing technique to sense the High side switch current when the switch is ON.The technique seems to work very well until the offset is introduced in the OPAMP.Due to this, the loop saturates as the OPAMP -ve terminal can not rise above supply and hence the loop takes a longer time to recover.
Pleaes pass on the feedabck so that I can solve this problem.
Thanks,
Captab
