I am reading App note AN-136 " COT Buck Loop bandwidth and Load step response comparison" for good reference .
But I have a question.
The settling time of MP1497S is written as 39.2us on Equation(15), but where should I refer
to this39.2us ?
Isn’t it 47.4us on page 8 Fig8, is it?
If my idea was correct, MP1497S bandwidth calculation should be 14.7KHz where theta=66.5degree.
