Power Management for FPGAs and Processors

With its robust and diverse portfolio of LDOs, power modules, DC/DC switchers, and PMICs, TI combines easy-to-use solutions with system expertise to help you find the perfect power supply match for your processor or FPGA.

Power for Broadcom, Cavium, and Barefoot processors

There are many high-current processors for wired networking and datacenter applications that enable scalability, high through-put, high density, full virtualization, and high performance along with power optimization. These are products such as Broadcom’s Strata XGS® Tomahawk processors, Cavium’s ThunderX2, and Barefoot Network’s Tofino that are optimized for Data Center and Cloud processors offering the highest level of integration and performance, and thus requiring very efficient, reliable, dense, and adaptive power solutions with intelligent digital interfaces and the tightest system accuracy.
