AN-32

The design of a switching power supply AN-32, by nature, is an iterative process with many variables requiring adjustment to optimize the design. The design method described in this document consists of two major sections: A design flow chart and a step-by-step design procedure. The flow chart shows the
design sequence at a conceptual level for AN-32 TOPSwitch-GX flyback power supply design. The step-by-step procedure gives details within each step of the design flow chart, including empirical design guidelines and look-up tables. All key equations and guidelines are provided wherever possible to assist the readers in better understanding and/or further optimization.
