#151987 - The frequency depends ...
Responding to: ???'s previous message
on how much experience You have on building these - and on how big You want the thing to be.

The lower the frequency the bigger transformer You are going to need.

I usually stay at the 100KHz region to keep the transformer reasonably small. This however requires a thoroughly thought layout. It also requires good drive of the MOSFET.

As said - it depends. I would try 50KHz and if feeling lucky - raise it to 100 KHz ..
