What is Digital Power In Summary?
Although "Digital Power" is a popular buzzword these days, especially by those companies who have developed or adopted the technologies, the bottom line will always be: "What do I get for my money?" At present, there are hardly any power supply or converter applications that "must have" digital power when compared to the many lower cost and field-proven analogue solutions that exist.
For example, during their new power-product design and development process, TDK-Lambda has designed in-parallel devices that employed both analogue along with those that use digital control ICs and technologies. In all cases, the final decision on which technology ultimately goes into production has been based on comparative price/performance factors; which is the dominant decision factor for their customers.
When the time comes that digital power products offer the same or better performance and reliability, along with the ”needed features”, at the same or lower price as analogue-based products, that is when Digital Power will become the winning technology. Realistically, someday digital power will provide a price/performance advantage over purely analogue power devices. Who knows for sure when that time will come.
