What is the most appropiate MOSFET (SW1,SW2,SW3,SW4) for this application?

My input voltage will come from a photovoltaic array, 4X260W panels connected in series(35Volts X 7.5Amps) Optimum so:

Vin Max: 140Volts @ 7.5 Amps                           Vout: 20-30 Volts

Vin Min:  30 Volts                                                 Max Current Out: 52.5 Amps

Max Current in: 8 Amps or 32 Amps if panels are connected in parallel.

    Looks like you'll need to use 150V MOSFETs for this application. Unless you are anticipating seeing much ringing in which case you may need up to 200V FETs. Unfortunately, TI currently has no plans to offer anything greater than 100V. Thanks for posting and let me know if you have any further questions.
