Abstract
A controller and an isolated power converter are disclosed. The controller includes: a bypass terminal coupled to a bypass capacitor; a first power circuit coupled to the bypass terminal and a first terminal, the first terminal configured to transfer electric charge from the first terminal to the bypass terminal; a second power circuit coupled to the first terminal, a second terminal and a third terminal, the second and third terminals coupled to a flying capacitor, the second power circuit configured to transfer electric charge from the first terminal to the flying capacitor; and a charging control circuit coupled to control the first or second power circuit to transfer electric charge to the bypass terminal, in response to at least one of a voltage at the bypass terminal and a voltage at the first terminal. The present invention eliminates influence of switching frequency variation and reduces sensitivity to an output voltage.
