an16TOPSwitch Flyback Design Methodology Application Note AN-16 Designing an off-line switching power supply involves many aspects of electrical engineering: analog and digital circuits, bipolar and MOS power device characteristics, magnetics, thermal considerations, safety requirements, control loop stability, etc. This presents an enormous challenge involving complex trade-offs with a large number of design variables. However, with TOPSwitch’s high level of integration, this design task has been greatly simplified. Because of the significantly reduced number of design variables and built-in loop stability, it is possible to develop a simple step-by-step design method that is easy to follow and quickly leads to satisfactory results. simplified version of the design method which, at imple……
