Hello,
We have 4 pth08t240w in our last board. 2 work, 2 don't (output voltage is down) They are practical copies of each other and all the input signals, feedback and senses seem to be as they should. The layout is also almost identical and we can apply voltage to the rails they are supposed to feed from other sources, so there are no shorts. Would you let me know hints about things I should be looking into?
Thanks!!
Best regards,
Pedro.
Hi Pedro:
I reviewed the application question.
Can you send me your complete schematic along with Remote sense connections, Rtt( Turbo trans resistors value).
The quantity output capacitance and ESR of the output capacitors, part number and type used on each output bus?
The tracking control function and its connection or how it is used or controllof the output voltage is very important

If you include your telephone number in the e-mail, I will call you after receipt of the requested data.
