Note 1. A flyback supply voltage of > 50V up to 60V is allowed in application. A 22–nF capacititor
in series with a 22
resistor (depending on I
O
and the inductance of the coil) has to be con-
nected between Pin7 and GND. The decoupling capacitor of V
FB
has to be connected be-
tween Pin6 and Pin3. This supply voltage line must have a resistance of 33
.
