Power Management is Moving from Static to Dynamic Control

Many engineers may not pay much attention to the power design, because they do not necessarily deal with power management issues everyday. Nowadays, the power supply and board power management is becoming more and more important.

IBA is short for intermediate but architecture, which is the most advanced power system today. It is composed of bus converters and digital point-of-load converters. Large companies in telecoms and datacom industry adopt this approach firstly, and then the medium-or small-sized companies also migrate to an IBA.

Today, engineers have to deal with a lot of new parameters when they consider power for a design, especially as FPGAs and Asics will usually need a number of different voltages over the system or board level design cycle.

The suppliers of power component should simplify this complexity and deliver something that is easy to use and reuse, while to keep it stable and sustainable. In order to help ease the know-how gap, the knowledge migration should be transferred from analogue to digital expertise among engineers.

What is more, the power management is moving from static to dynamic control on board level. The new generation digitally oriented designers want something that is easy-to-use to monitor and control power consumption. Certainly, they are familiar with simple and intuitive GUI-based tools, which ideally are also open source, so naturally they would also like a GUI for the power management similar to that available for FPGA or microprocessor based design.

To make the users able to manage and optimize board power in their designs at new and unprecedented levels of efficiency, the power component suppliers are now providing PMBus-based digital power component solutions together with easy-to-use GUI-based tools.
