TPS54350: About clock switching

Part Number: TPS54350
Other Parts Discussed in Thread: LMR23630, TPS54424

Hi,

I previously asked about clock switching in the following thread.
After that, when other threads are checked, the voltage fluctuation that occurs when switching from CLKmode to RTmode seems to be caused by the PLL inside the device.
The following devices do not appear to use the PLL internally when looking at the datasheet block diagram.
TPS54350, LMR23630
So I think that there is no voltage fluctuation when switching from the external clock to the internal clock, but is it correct?

By the way, the product I need is a product that can use an external clock with VIN of 12V or 24V, IOUT of 3A.
Best regards,
  • Hi Kaji,

    A similar question was asked earlier about clock switching, so yes you may try 

    TPS54350 or 

    TPS54424 (fig 34 in datasheet shows the typ performance between RT and CLK mode)

    that can take external clock with VIN of 12V, IOUT of 3A.

    regards,
