NOTES:
5. R2 and R3 are not required if the PMBus host already has I2C pull-up resistors.
6. Only one R4 per DDC bus is required when multiple modules share the same DDC bus.
7. R7 through R12 can be selected according to the tables for the pin-strap resistor setting in this document.
If the PMBus configuration is chosen to overwrite the pin-strap configuration, R8 through R12 can be non-populated.
8. V25, VR and VR55 do not need external capacitors. V25 can be no connection.
