What Is Digital Power System Management?
Nov 4th 2013
Power management of a high rail count circuit board can be very difficult with meters and oscilloscopes. There is a growing trend to configure and monitor power supplies over a digital communications bus. “Digital Power” or “Digital Power System Management (PSM)” allows systems designers to simplify ...
Experts Find There is More Analog in Digital Power Than Previously Thought
Feb 13th 2013
Last week at DesignCon there was talk of 100GigaBit SerDes: 4 channels of 25GigiBit. We all know that bits and frames fly over the wire, and at first glance these are digital communication systems. Yet Power Integrity problems involve Power Distribution Network (PDN) impedance over a large frequency range (DC-10Ghz) due to ...

Digital Power: Why Should I Care About Integration?
Dec 4th 2012
You have seen how Digital Power allows rails to work as a team, and how tools enable configuration and debug. Now it is time to step back and look at how Digital Power fits into a system. In particular, how Digital Power integrates with Board Controllers defined by industry standards.
Why should we care about standards?
In ...

Introduction to the Powerstick System
A picture speaks a thousand words, so let’s just cut to the chase and look at the hardware and software we will be using.
Above you can see three Powersticks, each with 14 rails, and one green LED per rail to indicate power. On the bottom right is a 12V DC input, and a DC1613A ...
Digital Power Sequencing
Aug 14th 2012
Power Sequencing is a key component of Digital Power Architectures. In this post we will take a look at several ways to architect sequencing, and its consequences. In particular, we will see how design choices impact flexibility late in the design process.
Building Blocks of Power Conversion
Let’s take a look at our ...
Digital Power Management
Jul 31st 2012
Many Digital Power products use the industry standard PMBus to enable system architects to manage and control multi-rail power architectures. However, many people are uncertain how to apply PMBus to solve real world problems. Over the course of the coming months I am going to blog on different topics related to the practical ...
