TPS25942A - About output capacitor

Hi Team,

The output capacitor (4.7uF+4.7uF+330uF) is mounted on EVM.

However, our customer would like to decrease the output capacitor.

So, they would like to know minimum value of output capacitor necessary to operate this device.

I understand this value is 0.1uF(ceramic capacitor).

Is my understanding correct?

And, could you please let us know if you have any concern?

Regards,

Kanemaru-san,
Reducing the output cap is not a problem. The 330uF cap on the EVM is there is imitate downstream bulk capacitance. For example, the input of a power supply.
