TPS62745: VOUT out of spec

Part Number: TPS62745


hi,

we are using TPS62745 in a new design, where SEL2 is toggled high/low to get 3.1/3.3V output (dual config system).

when we pull all SELx high we would expect 3.3V but we got roughtly 3.15V

as this part is pretty straight forward (all SELx pins connected to VOUT), may you provide any advice on what to look at?

what might cause the VOUT be so away from the regulation?

thansk a lot in advance
