Abstract:
1. A power converter, comprising: an input to be coupled to receive an input voltage; a switch coupled to the input; an input voltage sense circuit coupled to the input to generate an input voltage sense signal representative of the input voltage; a feedback circuit coupled to an output of the power converter, wherein the output is electrically coupled to the input, and wherein the feedback circuit generates a feedback signal representative of an output voltage of the power converter, wherein the feedback signal is a current signal and wherein the feedback circuit includes a voltage-controlled-current-source comprising a transistor coupled to generate the feedback signal in response to the output voltage; and a controller coupled to the feedback circuit and to the input voltage sense circuit to control switching of the switch to regulate an output current at the output of the power converter in response to the feedback signal and the input voltage sense signal.
