TPS62065: More ripple in one of the output same design higher ripple

Part Number: TPS62065

We are using two TPS62065QDSGRQ1 part in our design for 1.4V output and 3.3V output.

Both are having same input source, and for both we are using same 1uH inductor part.

But when we measure ripple we are seeing a minimum ripple on input of both the regulators, but the ripple on 3.3V output regulator is 4X times higher than the ripple on input side.

And on 1.4V side we are seeing a very minimum ripple which is lesser than the input ripple.

We have connected mode pin with pulldown, Is their any pin compatible FPWM supporting part. As we are facing issue in RE which we are suspecting from the 3.3V regulator.
