Hello to all.
Sorry for my poor english first.
I would like to make a BUCK,I need to a mosfet to use as a switch.
My switching frequency is 200Khz and the power I want to transfer is about 300w.
Is IRFB4110 good for this, I don't know what frequency it can switch.
Another question, Does it need to Heatsink?If you have better suggestion, tell me please.
thanks.
Hi,
You should really specify your input and output voltage too, and i guess you mean it is not synchronous.
