I am currently designing an buck-boost-converter that has an input voltage range from 10V to 50V and an output voltage range from 10V to 50V. It should deliver a output power of 500W over the output voltage range. So I decided to use this coil to suit my needs.
Coil: https://www.vishay.com/docs/59061/ipla.pdf
My converter should use an buck-boost converter IC with four switching mosfets and so I decided to use this one:
Converter IC: https://www.analog.com/media/en/technical-documentation/data-sheets/ltc7878.pdf
So my problem is to find the right mosfet for my application. I already know that my mosfet should withstand an dc current of more then 60A (80A minimum) and a voltage of around 50V (75V as a save zone) but it should work with the converter IC so the gate threshold voltage should as low as it gets for a power mosfet. Also the values of Qg, RDS(on), tr, tf and coss should also be as minimal as possible for better efficiency (less switching losses).
I dont know if its possible to find a mosfet with those requirements also it should move in the save operating area.
example mosfet: https://www.mouser.at/datasheet/2/196/Infineon_IRFP4468_DataSheet_v01_01_EN-1732903.pdf
I hope sombody can tell me if there is a better mosfet as my example mosfet and maybe somebody can tell me what gate voltage the IC can deliver for the mosfet.
