CHiL has implemented several digital algorithms in its digital power management IC families that combine to create a shaped efficiency curve.
Efficiency-shaping features save power from lowest to highest loads.
Tewksbury, MA– CHiL Semiconductor Corporation discusses its breakthrough in high efficiency computing voltage regulator (VR) solutions for CPU, GPU, and DDR applications in a podcast at http://bit.ly/9VgOKY.
Now configured to optimize efficiency from the lowest idle state to the highest operating state of today’s high performance server, graphics and desktop solutions, CHiL’s next generation true-digital power algorithms have increased efficiency up to 15 percent, especially at low loads.
Larry Spaziani, CHiL’s Vice President of Marketing, reviews how the efficiency of VR solutions has evolved over time, and explains how CHiL has achieved high efficiency improvements.

CHiL has implemented several digital algorithms in its digital power management IC families that combine to create a shaped efficiency curve. Dynamic Phase Control, the fast, controlled management of phases in a multiphase VR solution, combines the shedding of phases during average current, and extremely fast and controlled addition of phases during peak or transient currents as well as high average current.
CHiL also uses Variable Gate Drive, managing the gate drive to the MOSFETs or powerstage device during different load currents. It is programmable, so the user can tune it to optimize efficiency at low, mid and high currents.
“The recent trend includes integrated solutions, whether monolithic or multi-chip, which reduce parasitic losses and increase efficiencies at the low range,” says Spaziani. “CHiL has gone further and the shaped efficiency curve created by the combination of CHiL’s digital algorithms results in high efficiency across the entire load line.”
