FAIRCHILD AN4146 Manual

Update: 29 September, 2023

This application note presents the design guidelines for Quasi-Resonant Converters using FSCQ-series FPSTM (Fairchild Power Switch) in color TV applications. A Quasi-Resonant Converter (QRC) offers lower electromagnetic interference (EMI) and higher power conversion efficiency compared to conventional hard switched converters. It is particularly suitable for noise-sensitive color TV applications. The note includes practical design considerations for the transformer, output filter, sync network, component selection, and closing the feedback loop. The step-by-step design procedure described in this application note provides engineers with an easy way to design Quasi-Resonant Converters. Additionally, a software design tool called FPS design assistant, which incorporates all the equations described in this application note, is provided to enhance the design process. The design procedure is verified through an experimental prototype converter.
