Pulse to supply coupled Inductors for Volterra multi-phase chipsets

Volterra Semiconductor Corp. has selected Pulse as a supplier of multi-phase, coupled inductors for use with 4G regulator chipsets. Pulse is a Technitrol company, a provider of electronic components and passive, magnetics-based components.

Volterra's voltage regulator intellectual property, along with Pulse's coupled inductors, enables next-generation solutions needed for high-performance CPU and graphical processing units (GPU) used in personal computers, workstations, and servers.

Michael Arkin, Pulse power division product line manager, stated,"The Volterra chipset offers industry-leading ripple and transient performance, solving a difficult system problem in high-current, multi-phase voltage regulator module (VRM) applications. Combined, these products provide a low-risk path to the higher performance voltage regulator systems needed in these applications."

Bill Numann, VP of marketing for Volterra, added, "This topology serves as an important market driver for our scalable voltage regulator semiconductor chipsets. It allows our products to further reduce the need for external capacitor components in the voltage regulation system by a factor of two or more in high-transient applications such as powering CPUs and GPUs."
