Hi team.

We would like to put a capacitor at FLTpin for noise.

Can we use a capacitor?

We will use a 220pF capacitor.

If we can use a capacitor, is there a capacity restriction?

Sincerely.

Kengo.

Hello,

FLT is an open drain pin. The On-resistance for the FLT pin FET is not low. Putting capacitor on FLT pin is not an issue but the discharge time, when the FLT is low, is not very quick. I do not see any issue with small decoupling cap on FLT pin.
