The buck switchers support dynamic voltage scaling (DVS). The buck switchers are designed to directly
supply the processor cores. To reduce overall power consumption, core voltages of processors may be
varied depending on the mode the processor is in. The DVS scheme of the buck switchers allows to
transition between the different set points in a controlled and smooth manner.
For reduced current drain in low power modes, parts of a processor may be power gated, that is to say, the
supply to that part of the processor is disabled. To simplify the supply tree and to reduce the number of
external components while maintaining flexibility, power gate switch drivers are included.
