Other Parts Discussed in Thread: TPS23523,
Hello,
We have the evaluation board part# TPS23523EVM-863 and followed the procedure written in the user guide of TPS23523 but the board is not getting power up.
There are some differences in between the schematic of evaluation board and actual EVAL board such as :
1) many components are not mounted in the eval board as Q2,Q4 ,Q9,Q12 and many more.
We have provided +48V at J1 and GND at J4 but not getting the output at J2 and J5. Connector J7 and J8 pin 1 and 2 are connected via jumper.while J3 is left open.
We have checked TP8 UVEN pin w.r.t. Tp14 and getting voltage 0.56V less than 1V.
Kindly suggest what could be possible fault.
Regards,
Jainendra
