TPS62822: Switching frequency variation

Shinya Sawamoto

Part Number: TPS62822
Other Parts Discussed in Thread: TPS62823,

Hello team,

Can we know a rough value what is the switching frequency(or on timer) variation?
I'd like to estimate an output ripple by rough calculation with it.
Of course, we don't need it as guaranteed value but just as a reference.

Thanks in advance.

    Hi Sawamoto,

    For a reference, please see Figure 34. Switching Frequency vs Output Current for TPS62823 in the datasheet. You could find the range of frequency variation and use this as a reference for TPS62822.

    Please let me know if you need any further support.

    Regards,
