I have made a smps power supply as per the uc3843B datasheet indicates. the circuit is similar as the image given below:
The main problem is the snubber resistor (R5). I tried with 3K3/2W,5K6/2W,47K/2W,56K/2W,100K/2W,220K/2W,270K/2W. but all of them shows smoke within a few seconds. what is the problem and what is the solution here? please suggest.
C10=102/2KV
