APPLICATION INFORMATION
A converter with the TEA1507 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 1) 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
voltageat pin I
sense
(pin 5).The valueof thissense resistor
defines the maximum primary peak current.
An application note is available: AN00047.
