lm3488 sepic

I recently designed a LM3488 in a sepic configuration. I am noticeing a whine though at input voltages greater that 16 volts with a 1 amp load. The whine increaes pitch as the the input voltage increases. I am using 3.3uH inductors. What would cause a whine? Any sugestions on how to remedy this noise?
