Hi Sir

I'd like to ask for your help with the following:

The output capacitor of the TPS65150-Q1 8.2.2.5 has an rating Voltage of 16V and an output voltage of 13.5V .

Is there no problem if the rating Voltage is less than 1.5 times the output voltage?

Hello,

Normally the lower the rated voltage of the capacitor is, the higher the capacitance de-rating with the applied voltage. Although a 16V rated cap will work for 13.5V output voltage, it will be better to use a 25V rated capacitor.

Kind Regards,

Liaqat
