Patent ID: 8558484

Claim:
A power converter, comprising: a first winding; a second winding magnetically coupled to the first winding and electrically coupled to an output of the power converter; an output capacitor coupled to the second winding to provide the output to a load; a switch coupled between the first winding and the second winding such that a current flows through the first winding, the second winding and the switch when the switch is in an ON state, wherein the current that flows through the first winding has a value that is the same as the current that flows through the second winding, and as the current that flows through the switch; a controller coupled to control the switch to regulate the output of the power converter in response to a feedback signal; and a sense circuit coupled between the switch and the controller to provide the feedback signal, wherein the feedback signal is representative of an output current at the output of the power converter.
