Server and computer system architecture has increased in tandem with power delivery (PD) requirements in recent decades. This complicates regulator design since it necessitates a compromise between ...

Multiphase power conversion is virtually the only viable approach to handle today's multi-gigahertz microprocessors that devour 60A to 80A at 1.3V to 1.5V, and are moving toward 100A and higher with ...

Step-down (buck) voltage regulators have long been the preferred DC-DC conversion electronic workhorse thanks to their inherently high efficiency. Only in buck mode the current is directed to the ...

Although they are more complicated than their single-phase cousins, multiphase controller IC-based circuits provide better capability for powering the new generation of microprocessors. To understand ...
