Hi,
I noticed a lot of DC/DC converter(Buck and booset converter) have a clamp voltage at the output of the error amplifier.
I wonder why this clamp circuit is necessary? Is there any speciall considerations?
I found when I added this clamp block, the gain of my error amplifier is decrased a lot(from 55dB down to 25dB). What the priciples should I set the the clamp output?
Thanks
