Hi,

What's your output voltage? you can refer to below table to select the inductor. Thanks.

Hi Aurora

Thank you,

The output voltage is 3.3V When the input voltage is from 5V ~25V, will the frequency drop?

Hi,

Frequency reduction will occur during light load to improve light load efficiency. No frequency reduction when under heavy load or full load. When designing the inductor, it should be designed according to the output current and frequency at full load. Thanks.
