APPLICATION INFORMATION
A converter with the TEA1533 consists of an input filter, a transformer with a third winding (auxiliary), and an output stage
with a feedback circuit.
Capacitor C
during start-up and via the auxiliary winding during operation.
A sense resistor converts the primary current into a voltage at pin I
maximum primary peak current.
