Keysight Technologies Properly Powering On and Off Multiple Power Inputs in Embedded Designs Application Note This is the irst in a series of application notes that addresses power optimization, characterization, and simulation challenges in embedded designs. Introduction this is a costly measure that still has limitations in timing accuracy. The other option is to employ hardware-timed switching. This comes with If you are designing embedded systems, you face various power a high time overhead and extra cost, since you need to either create optimization and power characterization hurdles throughout the custom hardware or configure a DIO card to accurately time switch design process. You know what you want to output, simulate and closures. These sequencing configurations often need to be reconfig- measure--but you need a whole "toolbox" of instruments and ured each time the design changes or a new design is started. hardware to do the job. Properly configuring the various tools into an Setting up various slew rates on power inputs when you are using accurate, dependable solution can be difficult and time consuming. fixed regulator circuits requires some type of RC network at the output. When you need to rerun a test later, you may have to repeat the whole Once again, this is an inflexible solution since it cannot be easily time-intensive process of configuring your test setup. adjusted. Controlling slew rate on programmable power supplies may The challenges you face can be divided into three categories: properly be possible through programming if you are working with a high- powering on and off multiple power inputs, characterizing power performance supply. Otherwise, you will need to use some type of RC needs under dynamic load conditions and simulating real-world power network on the output of the supplies. conditions. This application note will focus on properly powering on and off multiple power inputs in an embedded design. We will discuss Product Features a simple way to overcome power sequencing challenges without the need for a costly toolbox of hardware. Solution The power input challenges embedded design engineers face can Properly Powering On and Off be solved with the Keysight Technologies, Inc. N6705A DC Power Multiple Power Inputs Analyzer. The N6705A provides four programmable power supply
