    Hello Shuai,

    That's a very large range for Vin and Vout.

    I found a reference design for for a 4-switch buck-boost that is very close to those requirements:  PMP21278.

    Vin = 9V to 50V, Vout = 12V, Iout = 25A.

    There is also a design for USB-C at 20V/5A/100W:  PMP10698.  Perhaps the design could be modified with higher power output components to deliver 300W.

    Vin = 9V to 42V, Vout = 20V, Iout = 5A.

    Regards,

    Eric
