Hi Yokota-san,

As for TLV62568, the switching frequency for TLV62568A is spec'ed typical only and we can't provide a min/max value.

fsw graphs over load and over input voltage can be found in Fig. 17 & 18 of the datasheet.

Best regards,
YD

Thank you for the reply.

Are there the min / max value as the design value?

Best regards,

If switching frequency is critical for the application I suggest to use a device with an internal oscillator which has specified min and max switching frequency, e.g. TPS62290 or TPS62060.
