Cutomer is seeing LTM4681 for VINT of AMD Versal HBM. They found leakage voltage ~160mV appears from Vout even RUN pin is GND. Why such leakage voltage happens? Is this expected behavior of micro module covering very high current? Vin=12V.
Hello
I'm experiencing the same issue with my evaluation board.
Could this be due to current leaking from the LTM4681's internal circuitry through the FET's body diode or other means, causing voltage buildup in the capacitor?
Or is this due to current leakage from the evaluation board's peripheral circuitry?
I'd like to know if the LTM4681 is the cause.
Also, I think I can set this to 0V by adding a resistor of about 1 kΩ to the optional bleeder resistors R175 or R176. Is this correct?
I'd appreciate a reply.
Best Regards,
Knj
