The digital landscape will be recast this year. Digital power management and
control is entering a new phase of commercial adoption with the introduction
of third-generation digital control technology. This includes: enabling new
power architectures through digital control techniques; the migration of
digital control into nearly all application segments; the adoption of digital
control in high-volume and cost-sensitive consumer devices; the realization of
adaptive control techniques in cost-effective controllers; the shift from
predictive to proactive real-time power system diagnostics with digital power;
and neural-based digital controller chips that will result in power supplies
that can "learn" and improve their performance over time.
Digital power management and control is on the cusp of widespread
implementation, and despite a slower economy, the technology developments are
not only likely to continue, but are likely to enable the very efficiencies
and cost-effectiveness that customers are looking for. The next couple of
years should see the emergence of an even more-established market for digital
control products.
