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 or connected to pin 9 (Vref, to avoid noise
sensitivity). With
1 mA and discharged slowly by
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).
