... DRAIN 8. Functional description The SSL1623PH 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 opto coupler feedback ...

... Only a power-on reset will restart normal operation. The short winding protection also protects in case of a secondary diode short circuit. 8.6.3 Overtemperature protection An accurate temperature protection is provided in the SSL1623PH. When the junction temperature exceeds the thermal shutdown temperature, the IC stops switching. During thermal protection the IC current is lowered to the start-up current. The IC continues normal operation as soon as the overtemperature situation has disappeared ...
