What is "openvreg"

OpenVReg stands for Open Voltage Regulator. OpenVReg is NVIDIA power supply specifications. It is an industrial first attempt to standardize both the package and pinout for low voltage DC-DC switching regulators.

The goal of OpenVReg is to enables packaging and pinout compatibility across multiple sources of similar devices with a single common PCB footprint and layout. OpenVReg defines the basic operation, the minimum set of features, the electrical interface and the mechanical requirements necessary to implement compliant devices.

OpenVReg compliant devices have:

• Non-conflicting pinout definitions: additional features are allowed but do not conflict with the base feature set.
• Circuit compatibility: devices function within the predefined reference circuit.
• Common layout: devices are footprint compatible.
• Mechanically compatible package: devices do not exceed the volume defined in the mechanical specification.

The current OpenVreg development focuses exclusively on DC-DC regulators and controllers. Future version may add definition for other types of devices. The current three OpenVReg regulator types are Type 0, Type 2 and Type2+1.
