 Hi, I am Paolo Sandri with ST Microelectronics and today I am going to talk about DC power distribution for data center. The recent increase in power demand for the digital azik is pushing the transition from a 12V DC bus to a 48V DC bus. The result is a higher efficiency of the power conversion which results in a better TCO for data center. ST offers a wide range of products for managing the 48V conversion and particularly we have two class of products that we offer or architectures. The first one is an architecture that is dual stage conversion, so we convert from the 48V down to an intermediate bus and then from this intermediate bus we go straight to the CPU or the digital point of load. The second class of products is a direct conversion from the 48V down to the point of load. For the two stage approaches we have different architectures. So we have unregulated architectures that are based on STC, switch the tank converter and this switch and tank converter is implementing a fixed conversion ratio. Most popular is 4 to 1 so that we go from 48V to 12V and we also have the regulated intermediate bus that is implemented by the newly developed STBAC that is providing 800W in 1.8 brick form factor scalable up to 3.2 kW with very good efficiency. The other class of products or architectures that we have are transformer based and they can serve both the intermediate bus conversion or the direct conversion straight from the 48V down to the CPU. The usage of these topologies are maximizing the system efficiency, the power density and the overall power distribution width of the shelf components and the goal is to maximize the efficiency of the whole system from the 48V down to the point of load.

Thank you very much for your attention and enjoy the rest of the show.
