Abstract
A secondary-side controller for an AC-DC converter that has a single synchronous rectifier sensing (SR_SNS) terminal, coupled to a synchronous rectifier (SR) of the AC-DC converter, and a voltage divider circuit coupled to the single SR_SNS terminal configured to provide signals to a sensing circuit. The voltage divider includes an active diode, an internal resistive element, and a switch, in which the active diode is configured to control the switch to enable or disable the internal resistive element based on a comparison result of a voltage at the single SR_SNS terminal and a reference voltage.
