Abstract
A control circuit and method for an isolated switching-mode converter are disclosed. The control circuit includes a primary-side controller and a secondary-side controller. The primary-side controller can enter a sleep mode in response to a first request signal, and the primary-side controller can turn on or off a first switch in the primary-side circuit in a predefined manner to cause a secondary-side winding in a transformer to generate a predefined first output signal. The secondary-side controller can detect the first output signal and responsively enter the sleep mode. In this way, both the primary-side and secondary-side controllers can enter the sleep mode, thus significantly reducing standby power dissipation of the system.
