Hi everyone.
we have designed using LM3489. Please refer attached images.
in all three cases input is 12 V. for 1st case(1st image) 3.3V output, 2nd case (2nd image) 5V output and for 3rd case (3rd image) 12V is the output
for 12V output, it is working fine. but for 3.3V and 5V output, IC is getting heated when connected to load.
Can anybody please resolve my issue.
