Part Number: TPS65150

Hello,

In the datasheet typical schematics and user's guide, there is 1nF of cap at the IN pin.

Could you please let me know the recommended capacitance and role of this cap?
I think that the recommended capacitance is 1nF and this is for LPF for VCOM buffer.

Bet Regards,
Ryuji

Hello Ryuji,

Is this question related to the other thread you just have opened? If so please use only one thread to handle the same application issue.

Thank you.

Hello Ryuji-san,

There is no minimum capacitance for this cap, it is supposed to filter out the noise, it Is not a must.

Best Regards.
