Abstract: A controller circuit for an AC-DC converter includes a first controller circuit block configured to drive one or more switches at the primary side of a transformer in the AC-DC converter. A second controller circuit block is configured to sense, at a secondary side of the transformer in said AC-DC converter, a secondary side signal indicative of the output signal from said AC-DC converter. The second controller circuit block generates switching control signals for the first controller circuit block as a function of the secondary side signal. An isolator circuit block between the first controller circuit block and the second controller circuit block includes an isolated transmission channel of the switching control signals from the second controller circuit block to the first controller circuit block.
