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 and R2 set the anticipation time by partitioning the V
voltage;
CC
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 V
CC
7) D3 could be necessary to protect CK pin from voltages higher than V
.
CC
8) SGLGND layout trace must not include OUT
current paths.
GATE1,2
9) A capacitor in parallel with R4 could be necessary to eliminate turn off voltage spike.
