Other Parts Discussed in Thread: PMP10099,
We have built up the PMP10099 according to the TI schematic and Gerbers.
The flybacks all work properly as supposed, unfortunately, as soon as more than one path is active, I can see a very low frequency variation in current of the parts involved, ranging from close to zero to complete current provided by one path all allone. I have 4 of the 8 soldered up.
In the schematic, there is a note which says that R12, R18 are for test purpose only. Taking out R12 doesn't help, taking out both cuts open the FB loop.
I am running out of options...
Regards,
Markus
