Maybe I’m running a little slow today, but when I first saw this product release, my knee-jerk reaction was to say to myself “What does POL stand for?”
I Googled POL to no avail. Eventually I bounced over to Ask.com, which led me to the Acronyms section of TheFreeDictionary.com. The most relevant entry for POL seemed to be “Point-Of-Load (DC/DC converter),” which would certainly seem to make sense … so unless anyone tells me otherwise we will go with that.
Of course I may be the only person on the planet (apart from my 80-year old mother) for whom the term “POL” was not immediately obvious. On the other hand, on the off-chance that others might have the same difficulty, it would be nice to spell this sort of thing out. Quite apart from anything else this would have saved yours truly a frustrating few minutes (grin).
Anyway, armed with our definition of POL, the rest of this release makes a lot more sense… well, sort of… see my additional notes at the bottom…
------ Start of Release ------ To meet the high-speed, low voltage, high current requirements of the latest FPGA designs, Bellnix has developed the BSV-1.8S4R0NA POL converter demonstrating unprecedented levels of performance including:
Ultra high-speed response using a new control system that is different from traditional PWM architectures
Small form factor, 11x11mm package, reducing PCB area by 50% and allowing positioning close to the FPGA
Low power loss switching element
Efficient heat treatment technology for high-efficiency
Partnership with two of the world’s largest FPGA manufacturers, Xilinx and Altera
Previous solutions required large value decoupling capacitors to decrease circuit impedances; however the high-speed response performance of the BSV-1.8S4R0NA significantly reduces this need.
The BSV-nano POL converter provides optimal performance for the latest FPGAs designs.
------ End of Release ------
So what’s the pricing and what's the availability? Where should one go to acquire these little rascals? Inquiring minds want to know (grin). The only additional information provided on the release was information about two companies as follows:
About Bellnix America, Inc.
Bellnix America, Inc. was established in San Jose, CA in November 2009 as a subsidiary of Bellnix Co., Ltd., a leading Japanese power supply manufacturer. Bellnix produces world-class products based on leading-edge technology and its products are used extensively by OEMs in the areas such as Enterprise, Communications, Telecom, Medical, Aircraft, Industrial and Test and Measurement.

Our headquarters are in New Jersey with locations in Germany, Hong Kong, and China, offering a global footprint to service your procurement needs and logistics-warehousing operations around the world.
Even Digikey has a POL category ;-) ( http://search.digikey.com/scripts/DkSearch/dksus.dll?Cat=4326594 )
POL converters, in my opinion, are often good alternatives to designing buck regulators; you don't have to pick a switcher IC and an inductor, plus they're overtemp/overcurrent protected and fully characterized.
An additional advantage is that DOSA (Distributed-power Open Standards Alliance) and POLA (Point of Load Alliance) ensure good availability and cross-compatibility from several manufacturers.
I've actually heard independently that Bellnix make good stuff and that this FPGA POL converter is all digital and is real good.
I also heard that the term POL is well known amongst power supply folks -- but I was also told that since the target for this release was folks alike me and FPGA and board designers, then it would have been a good idea to have explained what POL stands for (so maybe I'm not a *complete* idiot :-)
