LM5019: Output volatage is higher than calculated value

Part Number: LM5019
Other Parts Discussed in Thread: TPS23861,

Dear sirs,

I am making a application boad using LM5019 for supplying isolated 3.3v for TPS23861.

I followed same schematics as TPS23861EVM-613;

My schematic is as followw;

The values of L,R,C are same as TPS23861EVM-613 but our output voltage is about 4.0V.

(I expected 3.3V and I checked the output of TPS23861EVM-613 is excatly 3.3V)

Are there anything I have to check for this issue ?

I attached the schematic and layout for your reference.

Regards,
