Other Parts Discussed in Thread: TIDA-00652,
Hello,
I am New to power supply design have worked with Fly-back converters but new to Buck converter. I am have built the reference Design TIDA-00652 , but have a issue of R5 (0.05ohm) resistor blowing as soon as AC power is turned ON. So hot testing is not possible. Would appropriate help with information regarding how to go about testing and or any other reading material or detailed circuit description whic may help in solving this issue.
I have checked and rechecked the PCB and circuit and it is as per the circuit diagram no shorts on any kind.
Thank you and Regards
Dinar
