TEA1654
APPLICATION INFORMATION
A converter with the TEA1654 consists of an input filter, a transformer with a third winding (auxiliary), and an output stage
with a feedback circuit.
Capacitor C
VCC
(at pin V
CC
) buffers the supply voltage of the IC, which is powered via the high voltage rectified mains
during start-up and via the auxiliary winding during operation.
A sense resistor converts the primary current into a voltage at pin I
sense
. The value of this sense resistor defines the
maximum primary peak current.

The LOCK pin is used in this example for an additional external overtemperature protection.
If this pin is not used, it must be tied to ground.
