... A dedicated circuit for valley switching is built in, which makes a very efficient slim-line electronic power-plug concept possible. In its most basic version of application, the TEA1623P; TEA1623PH acts as a voltage source. Here, no additional secondary electronics are required. A combined voltage and current source can be realized with minimum costs for external components. ...

... DRAIN 8. Functional description The TEA1623P; TEA1623PH is the heart of a compact flyback converter, with the IC placed at the primary side. The auxiliary winding of the transformer can be used for indirect feedback to control the isolated output. This additional winding also powers the IC. A more accurate control of the output voltage and/or current can be implemented with an additional secondary sensing circuit and optocoupler feedback. The TEA1623P ...

... The short winding protection circuit is also activated after the leading edge blanking time. If the source voltage exceeds the short winding protection voltage V TEA1623PH stops switching. Only a power-on reset will restart normal operation. The short winding protection also protects in case of a secondary diode short circuit. ...
