LT8708 LTspice Simulation

Nothing jumps out at me as a problem. I recommend starting with the LTSpice macromodel. Ensure that works without changes and then change it one step at a time until you get to the topology you are interested in. If you are still having difficulty you can send me the LTSpice file to review.

Thank you so much for your help. It works.

Now, I want the output voltage is 56V for all values of input voltage between 40V to 54V. But it does not work . How can I fix output voltage?

Regards

I will need more detail or the LTSpice file to be able to provide any assistance. If you are not trying to get too much current output and the current is below the input and output current limit settings, an output of 56V is achievable.

Hi,

The output current is 10A. It provides  56V output in boot region forward direciton. But, For CCM, I need to provide in boost region reverse direction. Although the design satisfies all the conditions in the table, I cannot get a voltage in the VIN (reverse direction).
