This paper presents design guidelines for flyback power supply with HFC0400 of MPS as shown in Figure1. Design of a flyback converter with peak current control is quite simple and straightforward through the step-by-step design procedure described in this application note. Experimental results ...
This completes the design of the flyback converter. The transformer must now be designed to withstand the peak current values listed here, and it must have the inductances determined in Step 3. Q1 will also have some current limit; above this value the FET will burn up, or the current wi...
