did TI has any examples that the sync buck converter can be up to 95% efficicency under following condtion:
Vin = 20V
Vout = 4.2V
Iout = 8A
i used LMG5200 to do it ,but the efficiency just can be up to 90% under the conditon above
Is ZVS can be used to realize it ???
and is there any ZVS circuit that can be implemented to sync buck to refer?
