This document is an engineering report of an universal input 20W 5V off-line flyback converter power supply utilizing IFX F3R80 CoolSET® ICE3AR2280CJZ. The application demo board is operated in Continuous and Discontinuous Conduction Mode (CCM & DCM) and is running at 100 kHz switching frequency. It has a single output voltage with secondary side control regulation. It is especially suitable for small power supply such as DVD player, set-top box, game console, charger and auxiliary power of high power system, etc. The ICE3AR2280CJZ is the enhanced version of ICE3ARxx80JZ (CoolSET® -F3R80), the major new featrures includes slope compensation for continuous conduction mode (CCM), fast AC reset after latch enabled, fixed voltage brownout detect/reset.
