This training will begin with Analog Devices’ definition of digital power and the benefits that digital power brings. Keep in mind that the term “digital power” may be used by various companies to describe different things. At Analog Devices, digital power is defined simply as having digital control over an analog power system. A slow and highly accurate analog/digital control loop is wrapped around the DC/DC under control to provide accurate monitoring, sequencing, trimming and margining. This approach provides a number of benefits on a system level:  supplies can be easily configured via a PC for faster time to market, CPU performance can be optimized with real-time feedback, total system costs can be lowered, and digital communication provides easy interfacing to other system ICs to enable complete digital management from a desktop.
