Hello,

UCC39002 series are load sharing controller that must sampling each module's load current. and the two controllers needs current shareing signal connection.

Dear David,

Thanks for your reply.

Power sourcing are two 27V/120W adapters.

There are no any controllers in this scheme.

It only has VCC and GND traces on the adapters.

So Do we have any solution for this application without remote sense as below?

Thanks

Jimmy

Hi Jimmy,

if only VCC and GND is in the system, there is no analog current sharing IC can be used.
