Please check your input values of your=20
simulation. I guess the inductor is 220mH=20
(220E-3) instead of 22uH (22E-6). The LC-filter=20
doesn't reject the 50/60Hz from line it's cutoff=20
the switching frequence caused by DC/DC converter (~100kHz).

f =3D 1 / ( 2 * PI sqrt( L*C ) )          |       PI =3D 3.14159...
