Tool/software:
Datasheet specifies SYNC in frequency range 200...4000 kHz and lowest possible FSWEXT in the range between 95 and 115 kHz.
However, during the bring up of our push-pull dc-dc design we tried to set switching frequency to 80 kHz with RT > 1.07 MΩ. Load varies rather slowly, typical transitions are about 10-50 ms. Design was successfully validated at 25 deg C. What are potential downsides of running this part out of spec?
