A Novel Inverse Charge Constant On-Time Control for High Performance Voltage Regulators
… in processors. Another major issue for this ripple-based COTCM control is that when the combined inductor-current ripple in multiphase operation becomes zero because of the ripple-cancellation effect, COTCM loses its controllability. Therefore, the goal of this research is to discover a new …
