LTC3779 Vin=12V/24V, Vout=12V load regulation

Dear Sir,

When LTC3779 Vin=Vout=12V in different load, got different Vout values.

Do you know how to fix Vout=12V±0.2%(max)? Or the accuracy should be how much %  ?

Thanks.

If Vin=12V

Vo=12.05V at 10W

Vo=11.90V at 100W

Vo=11.70V at 200W

 

If Vin=24V

Vo=12.06V at 10W

Vo=11.95V at 100W

Vo=11.82V at 200W
