The digital power landscape is undergoing rapid change. Adaptive controllers,
parameter estimation and sophisticated control algorithms have become much
more economically reasonable to implement in a variety of systems. But there
is still a "perceived expense" of going digital, compared to using similar
bandwidth analog components.
Although digital solutions are still primarily being used in high-performance
applications, the pervasive emphasis on energy efficiency is pushing digital
from high-end-only into the mainstream. Digital control is now implemented in
just about all application segments, from catalog power supplies to power
supplies used in medical, solid-state lighting and consumer devices. In some
applications, digital penetration is already exceeding 50%.
With this broader implementation, along with expanded digital IC
functionality, digital power management and control is entering a
long-awaited "mainstream adoption" period. The next ten years will see
increased use of digital control, as applications demand power functions for
which digital is particularly suited.
