PMBus Description

The Power Management Bus PMBus is a two wire interface which is based on the SMBus bus. Refer to the SMBus page for physical layer information.
The PMBus is a protocol that defines communication between power conversion devices, using SMBus as the physical layer.

SMbus Interface Circuit

The Intermediate Bus Architecture [IBA] describes a possible interconnect.

Also refer to the I2C Bus or AccessBus page.
