Hello everyone,
I am trying to design a power supply for Arduino and other sensors from a 68V battery pack. The voltage outputs I require are +15,+5,-15. I am using an LT3958 for this reason. I have followed the design procedure according to the datasheet (linked here). When I do the analysis in LTSPICE I am getting a huge SW node ringing. It is 10V above supply. I have tried changing input and output capacitors without seeing much difference. I have attached my design files below.
For all those who can help thank you in advance.
