Digital Power Management

Analog Devices portfolio of digital power management products are specifically designed to meet the needs of the AC-DC and isolated DC-DC power supply OEMs. These devices are extremely flexible and have an I2C interface that allow for "real-time" reporting of key parametric data from the power system. The digital power products are highly programmable using an easy-to-use graphical user interface (GUI) tool. Power design engineers with no prior programming experience can use the GUI to monitor and quickly adjust power functions such as frequency, timing, voltage settings, and protection limits. In end-system implementations, these products help system integrators optimize power supply energy efficiency, while reducing design cycle time and enabling intelligent power management systems.
