Hello Team,

Thanks for your support.

Our customer will control the switching frequency of TPS57114C-Q1 by using external clock.

In case the external clock have variation then it apply more than 2MHz to RT/CLK pin, What happen in TPS57114C-Q1?

Thanks,

Hi Yuta,

This is not recommended as per the datasheet.
Do you know which frequency the customer is looking to apply at the CLK pin?

Regards,
Davor

Hello Davor,

The external Clock frequency is 2MHz±100ppm.

Thanks,

Hi Yuta,

In that case that shouldn't be a problem, since it is just 0.01% over 2MHz.
