I want a circuit to pass on ~5V DC at ~1-2A, but galvanically isolate it. Can somebody help? THX

    \$\begingroup\$ What exactly do you need help with, what do you have already? We don't throw designs at people. \$\endgroup\$ – PlasmaHH May 30 '17 at 12:57

    \$\begingroup\$ @user282088, an "isolated" DC-DC converter. \$\endgroup\$ – The Photon May 30 '17 at 15:52

What kind of dc-dc converter isolates galvanically?

Pretty much +90% of them.

If I look in Farnell I see there are 5640 isolating types and about 400 non-isolating types: -
