Digital Power Management and Power Rail Measurements

using High Definition Oscilloscopes Webinar

Date: Wed, August 21, 2019

Time: 11:00AM Pacific | 2:00PM Eastern

Modern electronic systems such as servers, data centers and complex embedded computing platforms including mobile and handheld devices require complex, yet reliable power delivery systems usually with several voltage rails that need to be applied in a specific sequence to power microprocessors, FPGAs, ASICs and other digital ICs. In such architectures, increasing the overall power supply efficiency is as important as managing the different rails by varying the voltages and changing the operation mode of power converters.  

Multi-phase digital power management ICs (PMICs) present unique testing challenges, especially in terms of understanding transient load response and load/current sharing/tracking. The recent advent of high bandwidth and high channel count oscilloscopes with high definition (12-bits) provide new capabilities for analyzing PMIC operation at the IC validation stage and also as designed into an embedded system when more than one DC power rail / PMIC operation needs to be analyzed simultaneously, or for specific single-rail power integrity studies.

This webinar will provide attendees with an overview of digital power management, power-rail measurements, and power-rail sequencing. Next, we will cover test approaches for single- or multi-phase digital power-management ICs (PMICs), as well as accurate and reliable measurement solutions for PMIC-based control systems, including analysis of such systems under transient load conditions.
