An Electronicstalk guide

Start with the news release DC-DC converter for point-of-load power designs from Toshiba Electronics, which we summarised at the time by saying "Toshiba Electronics Europe has launched an integrated digital DC-DC step-down converter that will save space and increase the design flexibility of point-of-load (PoL) power designs.". Several months prior to that, we featured the news release Ericsson Pola power modules based on Turbotrans from Ericsson Power Modules: "Ericsson Power Modules has added the PMR5000 (50A) and PMR8000 (40A) to its interoperable Pola product offering. ".

In July 2008, we covered the news from Murata Power Solutions - take a look at Adjustable power at the point of load which says: "New modules are ideal for supplying POL power to devices such as ASICs, FPGAs and DSPs in a wide range of multiprocessor digital systems.".

Take a look also at the news release from Exception Group, GBP 400,000 investment boosts PCB production, as well as POL modules cut down on capacitor demands from Ericsson Power Modules, and Regulators are easy answer to low-current demands from Ericsson Power Modules.
