Abstract
A multiphase DC-DC converter has two converter arrangements, each with a switching stage that has a switching node, an inductor, a converter output node, a high-side switch, and a low-side switch. Current sensing circuits detect the instantaneous current flowing through either the high-side or low-side switches, and signal time-averaging circuits produce time-averaged signals indicating the average current during a switch conduction interval. The time-averaged signals are added up and re-scaled based on the time period of the switching nodes' electrical coupling to the converter output nodes to generate an output signal for the average output current.
