Intersil launched a new platform product called the Digital Multiphase Family, which includes digital multiphase controllers and companion power stage products, that is a power solution for supporting infrastructures for data centers, wireless bay stations, networking switches, and routers. The platform supports high-current loads for devices such as memory chips.
The product is digital and can be tuned on the fly, changing quickly as the need arises. The multiphase controllers feature a digital compensator that helps power designers develop solutions that have no external compensation because device tuning is managed digitally with software. The company says that a complete power solution can be developed in 30 minutes compared to spending days managing RC tables with competing designs.
The product solution provides different interfaces, and all of them provide a PMBus for the data-out telemetry features. It also provides the adaptive voltage scaling interface (AVSBus), which is an interface between the device and the processor. The processor determines how much power is required and essentially tells the controller what it needs to support different tasks. The controller supports Intel, IBM, AMD, Broadcom, ARM, Qualcomm, and other processor chips. The product also supports optical transport, routers, and switches for wired infrastructure; base stations and line cards for wireless needs; and server, storage, and accelerator cards for the data center.
The solution features 12 digital multiphase controllers and a companion smart-power stage, including the industry’s first digital solution with an AVSBus. The new digital controllers provide up to seven phases assignable in any combination across two outputs and combine with smart-power stages to provide a scalable solution from 10 A to 450 A. The result is enhanced power optimization and more energy-efficient networking and communications infrastructure equipment.
