Abstract:
1. A way out of balance (WOB) rebalancer for use with a two-phase DC-DC converter that includes a pulse width modulator adapted to output a first pulse width modulated signal (PWM a first channel including a first driver MOSFET stage (DrMOS a second channel including a second driver MOSFET stage (DrMOS wherein the WOB rebalancer comprises: a WOB detector adapted to detect WOB conditions within the two-phase DC-DC converter; and a pulse path director adapted to adjust a balance between a current through the first channel and a current through the second channel in dependence on feedback from the WOB detector; wherein the pulse path director is adapted to provide one or more pulses of the first pulse width modulated signal (PWM selectively provide one or more pulses of the first pulse width modulated signal (PWM
