Abstract

Powering 5G applications requires end-to-end full-link energy saving design from the aspects of power supply, conversion, and power distribution. Improve the efficiency by power minimization and dynamic power management techniques have been widely explored in the past, however there is an important factor commonly ignored, which is the power conversion efficiency of a power delivery network (PDN). This article focuses on the efficiency of the PDN, introduces frequency domain techniques to optimize PDN designs and validate the efficacy of the proposed methods.

Introduction to multi-phase VRM design

Marlon Eguia (Monolithic Power Systems, US)

Nowadays server and computing system complexity has increased alongside power delivery (PD) requirements, which makes regulator design more challenging because it requires a tradeoff between higher efficiency and a fast dynamic response, as well as between reduced power loss and the size of the MOSFETs. The only way of meeting these demanding power supply requirements is the use of multi-phase converters, due to their power and current sharing capabilities. This tutorial will cover the main benefits of using multi-phase converters, and will offer a step-by-step design guide for a multiphase-phase buck converter.

Transient predictability for next generation of AI processors & Enabling fast transient response of the multi-phase VRM with TLVR

Jose Luis Silva (Monolithic Power Systems, US)

This tutorial demonstrates how to use the Simplis simulator to predict and optimize the power for the next generation of AI processors, whose requirements of high slew rates and current levels above 1000A are demanding faster transient response. Since multi-phase buck converters use non-linear features to mitigate this faster transient, it is essential to accurately model the converter behavior in combination with the power delivery network for the server platforms. By predicting the multi-phase buck converter performance and the transient droop and overshoot it is possible to reduce capacitance numbers and optimized their location in very early stages of processor design, moreover in case design specifications changes is possible to quickly assess their impact and to identify any potential problems in a more efficient manner.

​Power Delivery Network optimization for 5G Applications

Marlon Eguia

Powering 5G applications requires energy-saving design from the aspects of power supply, conversion, and power distribution. Improving efficiency by power minimization and dynamic power management techniques have been widely explored in the past, however, there is a crucial factor commonly ignored, which is the power conversion efficiency of a power delivery network (PDN). This tutorial focuses on how to achieve an efficient power delivery network (PDN) design by minimizing the parasitic behaviors of the components in the PDN during the design process. The bypass and decoupling capacitors are essential components in the PDN and their placement requires special consideration since insufficient capacitance can lead to system instability and performance issues.
