ABSTRACT:
In one embodiment, a power supply controller generates a PWM control signal that is subsequently used to control a portion of current flow in a primary side of a power supply system. THE PWM control signal is coupled to a secondary of the power supply system and used to control a synchronous rectifier that is coupled within the secondary side.
