Hello team,

How to estimate switching frequency when Iload is under 0.8A in PFM mode?

Do you have a plot for switching frequency vs output current?

Best Regards,

    Hi Austin,

    Here is a plot of switching frequency vs load for 5V VIN and 1.8V output using our EVM BOM.

    You can also use our Webench tool (https://webench.ti.com/power-designer/switching-regulator ) to estimate the PFM switching frequency.

    Best regards,
