Figure 3 : STSR30 SYNCHRONIZATION TECHNIQUE
The synchronization is based on the revelation of the low level of the drain voltage of the synchronous rectifier. To avoid false triggering of
the device during discontinuous mode, it is important that the lowest level of the ringing must be higher than the Ck threshold. Diode D3 and
resistor R3 keep the Ck signal to high level even during the ringing. OUTGate is the complementary signal of the Ck with proper dead time
setting to avoid cross-conduction.
