Two of the most recent trends in high performance DPA (Distributed Power Architecture) systems are the need for extremely fast transient response and the usage of IBA (Intermediate Bus Architecture).

With the ever-increasing complexity of today’s printed circuit boards, the many voltages required to properly power all the integrated circuit loads are now managed by a range of point of load (POL) ...

Find a downloadable version of this story in pdf format at the end of the story. Processor-based systems place strenuous voltage regulation requirements on their power supply. In many instances, this ...

The multichannel, interleaved QSW VRM uses a novel current sensing and sharing technique to improve transient response and minimize supply size. Advances in microprocessor technologies will impose ...
