Dear:
When I use LP8861-Q1, there is a problem of inductance whistle. When the problem occurs, the SW pin waveform is as shown in the figure, the yellow is connected to the SW pin, and the green is connected to the PWM pin. When I changed the PWM frequency from 5K to 16K, the waveform on the SW pin was continuous, and the inductor no longer had any noise.
Can the waveform of the SW pin be continuous without modifying the frequency of the PWM signal, so that the inductor no longer makes any noise?
