Abstract

A power supplying circuit includes a rectifier, a flyback converter, a power factor correction circuit, an LLC resonant converter, a power factor correction (PFC) controller, and a LLC resonant controller. The PFC controller is configured to supply a first operating voltage to the PFC circuit. The LLC resonant controller is configured to supply a second operating voltage to the LLC resonant converter upon a condition that a voltage applied on the output terminal of the PFC circuit reaches a predetermined voltage.
