Digital Multiphase Controller
for Core Power
as microprocessors and aSICs have grown in power and complexity, their voltage regulation
requirements have become increasingly demanding. This growing complexity has led to the introduction
of Primarion Digital Power Management (DPM) solutions with increased accuracy, real-time monitoring
and control capabilities via digital communications bus. The simplified system design the DPM solution
provides leads to lower cost and higher performance implementations.
Primarion’s Core Power ICs are designed into voltage regulator modules (vrMs) and motherboards for leading
server original equipment manufacturers (oEMs) and are currently shipping into major server oEM systems to
power CPU and GPU.
Primarion’s digital power system-level solutions enable improved digital control features: better accuracy and
use of lower cost passive components through adaptive digital calibration, improved ability to respond to fast
changes in power requirements (transients) using fewer external capacitors with proprietary active Transient
response (aTr), and easier design-in with a graphical user interface. Primarion’s overall solution requires
substantially fewer components and associated costs as compared to current analog power solutions.
