Hello, I simulate with LT-Spice the circuit of EVAL-LTC7872-AZ, the Buck-function is working without problems. But the Boost configuration is not working. It is not possile to boost from 14V to 48V. The values are the same as in the Eval Board. It seems that the model in LTSpice is not working well for a Boost configuration. You may have a reference Boost LT-Spice Design with the LTC7872? Thank you and best regards Dani
