 Hello, I am Paolo Sandri with ST Microelectronics and today I will talk about ST products and solutions for modern data centers. ST offers a wide range of products and solutions for modern data centers to address the key three challenges of the data center ecosystem. The first one is the energy efficiency and the power density. The second one is the data management and the third one is the scalability. This is an example of a typical rack server architecture and it shows the ST coverage in terms of products and solutions. At the bottom we have the first stage which is a power supply unit that converts the AC line to a DC line. Usually DC line is either 12V or 48V, 48V is the new DC bus for higher efficiency and ST offers several key products for the AC to DC efficiency and power density optimization. Then the 48V line DC bus that is usually distributed with a bus bar is distributed through a 48V fuse. The 48V fuse has a current capability up to 28A and it is scalable, meaning that it can be parallelized, interleaved to adapt to the different loads that are required by the specific application. Then the 48V is a converter with an intermediate bus converter and there are two fundamental topologies that ST offers. There is the unregulated topology and the regulated topology. The unregulated topology for example here is shown the STC, the switched tank converter, and it implements a 4 to 1 conversion ratio and it can deliver up to 1 kW thermal design power in a 1.8 brick form factor, so very high density, very high efficiency above 98% and very low profile. Then we have a series of converters that are regulated with the ST back, the ST converter that we invented and this is an example, a reference design of a stocked back coupled inductor converter that is also managing up to 1 kW thermal design power with the possibility to interleave up to 4 cells for a total of 4 kW. Again, characteristics of this topology is extremely high efficiency, very flat efficiency curve and interleaveable operations to address the scalability requirements for data centers. Then the unregulated bus is distributed through a 12V high current diffuser, 60A 12V diffuser as input of a multi-phase voltage regulator with ST digital controller multi-phase and a smart power stage SPS 4x6. This is an example of 16 phase power delivery for CPU VR and the characteristic of this is a very high efficiency and the maximization of the efficiency across all the entire load range thanks to the phase shedding, so scalability by design of this solution. On the regulated bus, the 12V regulated is needed because there are loads that are requiring a regulated voltage like the HDD, this driver or the SSD or the PCI Express. So the 12V regulated bus is distributed through a low current diffuser and in SSD we have the leadership in the power combo helping to enhance the HDD capacity. So again, we address the data management with innovative power combo solutions and also we are presenting the PMIC for SSD enhancing and maximizing the efficiency and reducing the number of components. In addition to all these systems and devices we have a rich family of sensors, temperature, pressure and accelerometer to constantly monitor the data center operations to guarantee a 24-7 activity which is very important for the data center. So this is an example of a few innovative solutions that we are providing and this is the HSTC, the hybrid switch and tank converter which is another ST topology, invented topology that addresses the conversion ratio higher than 4 to 1, for example 5 to 1, 6 to 1, 8 to 1, 10 to 1 and so on with the characteristic of having the same number of components because it's a topology that is transformer based. So this is the latest reference design that we have with 25 by 19 millimeters delivering up to 750 thermal design power and this is very useful for the unregulated intermediate bus power delivery where the extreme high density is needed. On this side there is a reference design for a 32 phase multi-phase digital voltage regulator using the ST multi-phase digital controller and the ST SPS 4 by 6 and this is an example on how to address the very high power requirements for artificial intelligence and machine learning chipsets. Of course also in this case the control scheme is the same and there is an efficiency maximization due to the phase shedding with a lot of additional features for telemetry and for security. The third board on the counter is the ST Spin 32 that is the core engine for the liquid cooling pumps. So in essence what ST offers for modern data center is an ecosystem of solutions, products and reference design and solutions to address the challenges of energy efficiency and power density, the data management and the scalability.
