I try to run TOP261LN by 100 wt at 130KHz by grounding pin F, but chip run at 66 KHz.
What is the problem.

You have to double check your connection. If F pin is really connected to S pin, and the frequency is 66kHz, then I would like to doubt the source of the parts. As you know, a lot of customers use TOPSWITCH for different applications, and it is incredile that TOPSWITCH has this problem.
