I want to design a power supply with the following specs:
Vin: 11-13V (12V nominal)
I have followed the data sheet and calculated the key components and I am doing some simulations with LTSpice to get acquainted with it and to have an idea of the expected behavior of the power supply. Please see attachment below.
One difficulty I am having is the data sheet does not provide much infomation about how to calculate the compensation network. I noticed some instability when there is a current step on the output. Is there a way to improve this?
Regarding the soft-start, how is it calculated?
Thanks in advance.
