I have a problem to servicing of a DTH smps.There is a 8Pin IC (Viper 22A is printing on it),but when I connect a new IC(Viper 22A)fuse is Blown.I am sure it is not Viper.Can any body tell the exact Number the IC.
Connection are that is Pin 7,8= Drain,Pin 1= +HVDC through a resistor,Pin3=Ground,Pin 4 680pF to Gnd,Pin 6=1.5Ex2 resistor to Gnd,Pin2= VCC,Pin 5= Opto-coupler.
