If you're waiting on digital power, you're backing up says Darnell Group

March 12, 2007

The Darnell Group, a market research and publishing firm covering power electronics, released its most recent findings on digital vs. analog power supply controller pricing, and states that digital power has started to reach price parity with analog controllers. Darnell predicts that digital controllers will cost less than analog controllers by the end of 2008. So not only will digital power enable cost savings at the system level due to increased energy efficiency, but dropping parts costs will make the BOM for digital power control lower than the equivalent for analog control. Expect to see digital power working its way into all but the most basic power supplies by the end of the decade.

UPDATE: Here's the link to Darnell's press release. (Thanks, Jeff.)

(Darnell also puts on the Digital Power Forum, September 10-12, San Francisco.)

Paul, Very interesting comments from your side, and Jeff very comprehensive reply, I am impressed by all of you! Whatsoever, as having the chance to be part of a company that does both, dc/dc power supplies and telecom equipments, I am please to see the both ends from component to end-users of telecom?s equipments. Maybe wise for you Paul, to read my latest article known as ?From Digital Confusion to Digital Conversion? which you could access by searching on Internet. As I said in preamble I have the chance to have an overview of what Digital could bring as benefit to our customers and as you know, energy preservation becomes a very important for all of us but total cost of ownership is also an important factor to consider. We could debate a lot about the number of junctions at silicon level but I rather prefer to invite you to read different papers that we presented at DPF-2006 and the one we are going to present week 0712 at PCIM China 2007. You will see tangible examples of what Darnell highlighted in their article, and very soon realize that power community has moved ?From Digital Confusion to digital Conversion.? To end my entry to this Blog, be free Paul to contact me at any time (I?m sure you will find your way to reach me.)
