Im using a PWM, with a feedback op-amp supplied, im using DC input. My quistion regards v+ and v- (opamp-inputs), i want to control v- by adjusting input voltage to v+, the thing is this happens over a small voltage range. I was wodnering what factors can be done to increase that votlage range, and why in the first place is it being contolled for only a small voltage range.
thanks.
p.s i can add a pspise image of the real circuit, if u need more clarfications.
