7.3 Features Descriptions
7.3.1 Multi-Phase DC/DC Converters
A multi-phase synchronous buck converter offers several advantages over a single power-stage converter. For
application processor power delivery, lower ripple on the input and output currents and faster transient response
to load steps are the most significant advantages. Also, since the load current is evenly shared among multiple
channels, the heat generated is greatly reduced for each channel due to the fact that power loss is proportional
to square of current. Physical size of the output inductor shrinks significantly for the similar reason.
