Designing an off-line power supply involves many aspects ofelectrical engineeringanalog and digital circuits, bipolar andMOS power device characteristics, magnetics, thermalconsiderations, safety requirements, control loop stability, etc.This represents an enormous challenge involving complextrade-offs with a large number of design variables. As a result,new off-line power supply development has always been tediousand time consuming even for the experts in the field. Thisapplication note introduces a simple, yet highly efficientmethodology for the design of TOPSwitch family basedoff-line power supplies. For TOPSwitchdesigns.
