More Data, More Apps, More Mobile…

I don’t know about you, but in my house the number of mobile devices seems to multiply overnight, along with the ways they are used.  On any given night, you may find me on a GoToMeeting conference on my laptop, my husband on a video Skype chat from his phone with his dad in Florida, my oldest son turning in an assignment on Google Classroom from his laptop, my younger son streaming videos on his tablet, and my second grader recording and posting a music.ly on her phablet.  And when we travel, these devices come with us so they need to be small and lightweight enough to come along for ride! 

This all translates into ever-increasing power demands for computing and telecom systems and the conflicting desire for small, lightweight form factors, and extended battery life. To meet these demands, point-of-load (POL) DC-DC converters (the power engines) need to be designed to be small sized and as efficient as possible. These demands translate to ever faster switching frequencies of the transistors used in the power conversion running these devices. Notebook PCs, tablets, and phablets are especially sensitive to this need as our dependency on these devices and the demands we make on them continues to grow.
