TDA 4601
In case of continuing problems of disturbance (

/2 – 0.1 V) the switch-on mode is interrupted
by the periodic protective operating mode described above, i.e. pin 8 is inhibited and
V

is falling,
etc.
Switch-On in the Wide Range Power Supply (90 Vac to 270 Vac)
(application circuit 2)
Self-oscillating flyback-converters designed as wide range power supplies require a power source
independent of the rectified line voltage for TDA 4601. Therefore the winding polarity of winding
11/13 corresponds to the secondary side of the flyback converter transformer. Start-up is not as
smooth as with an immediately available supply voltage, because TDA 4601 has to be supplied by
the start-up circuit until the entire secondary load has been charged. This leads to long switch-on
times, especially if low line voltages are applied.
However, the switch-on time can be shortened by applying the special start-up circuit (dotted line).
The uncontrolled phase of feedback control winding 15/9 is used for activating purposes.
Subsequent to activation, the transistor T1 begins to block when winding 11/13 generates the
current supply for TDA 4601. Therefore, the control circuit cannot be influenced during operation.
