TPS22990: Is there a maximum CT(pF)/output rise time spec?

PY (Pengyu) Song

Part Number: TPS22990

Hi team,

In datasheet, the maximum CT cap is up to 10,000pF (10nF) and output rise time is up to 598.5us (VIN = 5V). 

I would like to know if CT cap can be increased to, say ~200nF in order to increase output rise time to ~10ms+? 

Thanks!

    Hi Pengyu,

    The CT capacitor does not have a maximum value, but exceeding the table limits may cause concern from a thermal perspective depending on the loading conditions. In your application, what is the load capacitance and load current on the output of the TPS22990?

    Thanks,
