Hi Team,

just want to check what Fsw is when Rt is floating. Is it 200khz since floating is high impedance? Thanks.

Hi Given,

We recommend not to leave the pin floating. The pin is also working as a CLK signal input. If left floating, this could lead to unwanted behavior, if noise is captured on this pin.
