I am using this Buck Converter 2A part.
I am giving an input voltage of 3.3V to get an output of 1.2V for a switching frequency of 2.25MHz.
I am giving different load currents of 0A, 0.2A, 0.5A & 1A. But why is my switching frequency like below:
Why is my switching frequency like that? I am measuring the switching frequency at the SW pin of the IC (before the inductor).
