MPS3550E - Switching Frequency Range

Hi,

I have inherited a design that uses the MPS3550E, and am curious about the allowed switching frequencies for this part. The datasheet specifies a range of 457 - 557kHz for the switching frequency, but it seems that is the expected switching frequency for the given parameters (VOUT = 5V, TA = 25°C, RFREQ = 100kΩ ), and not a valid frequency range.

What are the lower/upper limits on the switching frequency of the MPS3550E?

Thanks!
Cory
