Fixed Frequency and Synchronization Circuit SYN (Pin 7)
Figure 11 shows the Fixed Frequency and Synchronization Circuit. The circuit is
disabled when Pin 7 is not connected. With
R
7 and C7 at Pin 7 the circuit is working. C7
is charged fast by approx. 1 mA and discharged slowly by
R
7 (Figure 11). The power
transistor is switched on at beginning of the charge phase. The switching frequency is
(charge time ignored)
:
When the oscillator circuit is working the Fold Back Point Correction is disabled (not
necessary in fixed frequency mode). “Switch on” is only possible when a “zero crossing”
has occurred at Pin 3, otherwise “switch-on” will be delayed (Figure 12).
