TIMING DIAGRAM

APPLICATION INFORMATION: STSR2 IN FORWARD CONVERTER SECONDARY SIDE

NOTES

1) Ceramic Capacitors C1 and C2 must be placed very close to the IC;

2) R1 andR2set theanticipationtimeby partitioning theVCC voltage;

3) R3 and R4 is a resistor divider meant to provide the correct CK voltage range;

4) R5 limits the current flowing through diode D2 when Freewheeling drain voltage is high;

5) D1 could be necessary to protect INHIBIT pin from negative voltages.

6) D2 could be necessary to protect INHIBIT pin from voltages higher than VCC

7) D3 could be necessary to protect CK pin from voltages higher than VCC.

8) SGLGND layout trace must not include OUTGATE1,2 current paths.

9) A capacitor in parallel with R4 could be necessary to eliminate turn off voltage spike.
