To support the evolution and expansion of Cloud services, the Internet of Things and mobile apps, the demand for data centers is growing exponentially with more powerful CPUs and extended memory banks making efficiency and power density a daunting challenge along with enhanced reliability.

In a typical architecture, a 48V DC rail is generated from the AC-DC power supply unit that will then be converted to provide the number of DC rails needed to supply the variety of loads and circuits in the server. This conversion must meet stringent efficiency targets requiring innovative architectures like those developed by the Power Stamp Alliance (PSA) for direct conversion from the 48V rail.

We offer a range of high-efficiency DC-DC conversion solutions including an isolated, single-stage direct 48 V to the Point-of-Load (PoL) resonant, conversion solution for CPUs and DDR memories based on the Power Stamp Alliance (PSA) product footprint and compliant with Intel VR13 and VR12.5 specifications.
