Embodiment Construction

[0015] Embodiments described herein relate to a DC / DC converter comprising a first stage for converting a high bus voltage to an intermediate bus voltage and a low bus stage for converting the intermediate bus voltage to power a load such as a CPU second level of voltage. The load communicates with the DC / DC converter using protocols for status, protection and system optimization. Part of the optimization process involves the load instructing the second stage to change its operating set point so that the light load efficiency of the second stage can increase when the load enters a low power state. The first stage is aware of the load's intention to save power, for example by monitoring communications between the load and the second stage or by receiving communications directly from the load. In response, the first stage changes its operating set point so that the amount of current delivered to the second stage is reduced. In this way, the first stage implements a desired pow...

Abstract

The invention relates to an intermediate voltage bus converter with power saving modes. A DC / DC voltage converter includes a first stage operable to convert a first DC voltage rail to a second DC voltage rail different than the first DC voltage rail and a second stage operable to convert the second DC voltage rail to a third DC voltage rail lower than the second DC voltage rail and deliver current to a load at the third DC voltage rail, the amount of current delivered to the load corresponding to an operating set point of the second stage. The second stage is operable to change its operating set point responsive to a command received from the load, such that the amount of current delivered to the load is reduced. The first stage is operable to change its operating set point responsive to a command issued by the load, such that the amount of current delivered to the second stage is reduced.

Description

technical field [0001] The present application relates to intermediate DC / DC voltage bus converters, and in particular to entering and exiting a power saving mode through an intermediate DC / DC voltage bus converter. Background technique [0002] To save power in data centers and other data-intensive applications, the typically 12V DC distribution bus can be replaced by a higher voltage bus (eg, typically 48V nominal). On the motherboard, this higher distribution voltage is stepped down in one or more stages to the CPU (Central Processing Unit), memory, and components included in the system such as memory, graphics logic, I / O (input / output), etc. Low DC voltage required by other electronic components. For example, a single DC / DC converter conventionally generates an intermediate bus voltage that is fed to all lower voltage converter stages. The intermediate bus voltage is typically between 5V-12V and thus highly scalable existing infrastructure can be used. In another exam...
