Using digital control in power supplies is considerably more flexible than analog control in its ability to adapt to changes and digital control inside the power supply results in advantages to the system application such as improved efficiency, fewer external components and reduced overall cost.

The embedded digital control circuitry in the power supply can also be used for system power management purposes. Flexibility is the key and the power system designer may choose features and capabilities that are important to a specific application.
