Other Parts Discussed in Thread: LM5023
Hello
Iam designing PFC based battery charger. i am using the reference design of the auxiliary power supply given in the PMP8740 reference design(https://www.ti.com/tool/PMP8740#tech-docs) and (https://www.ti.com/seclit/ml/slup348/slup348.pdf?ts=1669636312598&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FUCC28180). schematic diagram of the circuit and the real hardware board are given below. when we supply rectified AC output to the RF1 fuse, the resistor R47(Rsense) got short circuited. we are unable to find the actual fault for this short circuit. for this purpose we inspect every component placement thoroughly and everything seems to be fine. can you please help us in this regard.
Thanks
