TPS2363: About TPS2363 Power Switch Fail Question

Part Number: TPS2363


Hi Sir,

My customer plan use TPS2363 design PCIe Card. verfication TPS2363 has abnormal behavior need you help.

Found that the TPS2363PFB (power switch) has some behavior unlike datasheet written as follows:
Enable power controller when Enable and AUXENA connect to high. but MOSFET cannot turn on.
We have confirmed that the /FORCEONA/B to GND can turn on MOSFET.

There must be other mistakes which cause the power unable to be switch on/off.
If you can think of other point, please share with us….

Also can share TPS2363 GUI to me? thanks.

  • Duke, 

    We will take this offline as it will take some time to go through the schematic and back and forth with debug.  See email.
