Hi,
I would like to ask hot o determine switching frequency for a MOSFET by looking at the datasheet.
Most of the datasheet don't provide such information but they provide the following times:
Switching on time [ton], raise time [tr], falling time [tf], switch off time [toff]
example:
- Toff (Switching Off time) [nS] 14
- Ton (Switching Oontime) [nS] 10
- Tr (Raise time) [nS] 13
- Tf (Fall time) [nS] 7.5
Total cycle time = 44.5nS therefore:
Fsw=1/T = 22Mhz.
Would this be right ?
