Multi-Output PowerSoC Converters

With the increasing number of power rails in systems today, using a multi-output PowerSoC is a way to reduce the number of independent ICs. These multi-output devices deliver high-power density and are ideal for space-constrained applications that cannot sacrifice performance.

To deliver a high level of integration, multi-output Intel® Enpirion® PowerSoCs are designed, characterized, and qualified as a complete power supply system, resulting in a low risk solution. Using these multi-output PowerSoC products will reduce the number of components required in the system and improve system reliability versus discrete power supply solutions.
