Hello
I am doing a 15W offline flyback (230VAC) using TOP254 controller with on-chip FET.
I need to calculate the switching losses before i build the prototype,
However, the TOP254 datasheet does not give the necessary information about the on-chip FET in order to calculate the switching losses.
Here is the TOP254 Datasheet:-
http://www.powerint.com/sites/default/files/product-docs/tophx_family_datasheet.pdf
I need the following data:-
Q(g)
Q(d)
Q(g) total
Driver current level of on-chip FET driver.
Output resistance of on-chip FET driver.
None of this data is available on the datasheet, so how may i calculate the on-chip FET switching losses?
