The TEA152x family 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 TEA152x family uses voltage mode control. The frequency is determined by the
maximum transformer demagnetizing time and the time of the oscillator. In the first case,
the converter operates in the Self-Oscillating Power Supply (SOPS) mode. In the latter
case, it operates at a constant frequency, which can be adjusted with external
