Description
The aim of this design guide is to assist the designer through the steps needed to complete a design using the C2183 power controller. The primary side sensing (PSS) controller is designed to drive an external power MOSFET switch in a Discontinuous Current Mode (DCM) quasi-resonant flyback converter. The block diagram for the IC is shown in Figure 1. A generic circuit diagram of a converter is shown in Figure 2 below. Use this document in conjunction with the C2183 datasheet, which lists the IC parametric values. The C2183 is a primary sensing switching regulator. It is intended for applications where constant voltage and current operation is required. […]
