For EMI purposes I need to know what is the highest frequency used (like clock frequency) in the circuit?

I dont know what integrated circuit is mounted on pcb. The type is scraped off. I think it is an LM22680 from National.
The switching clock frequency is provided by an internal fixed frequency oscillator which operates at 500kHz. The switching frequency can also be adjusted with an external resistor or synchronized to an external clock up to 1MHz.
