11. Application information
A converter with the TEA1532 consists of an input filter, a transformer with a third winding
(auxiliary), and an output stage with a feedback circuit.
Capacitor C
VCC
buffers the IC supply voltage, which is powered via the high voltage
rectified mains during start-up and via the auxiliary winding during operation.
A sense resistor R
sense
converts the primary current into a voltage at pin SENSE. The
value of R
sense
defines the maximum primary peak current.
Figure 10
shows a flyback configuration using the discontinuous conduction mode.
Pin PROTECT is used in this example for external overvoltage protection and open loop
or output short-circuit protection. If this pin is not used, it must be tied to ground.
Figure 13
shows a flyback configuration using the continuous conduction mode. Pin PROTECT is
used in this example for external overtemperature protection and open loop or output
short-circuit protection.
