Modeling and Stability Analysis for Multiphase Constant On-Time Control With Phase Overlapping
Multiphase buck voltage regulators (VRs) powering today's high-performance processor loads must regulate output voltage within a small tolerance window and handle a large steady-state current. For output voltage regulation, multiphase current-mode and V² constant on-time (COT) control techniques …

Control and Modeling of High-Frequency Voltage Regulator Modules for Microprocessor Application
… trajectory control is then extended to multiphase COT. For multiphase operation, additional operating behavior, such as phase overlapping during transient and interleaving during steady-state, need to be taken into consideration to design the desired state-plane trajectory control. A simple …

A Novel Inverse Charge Constant On-Time Control for High Performance Voltage Regulators
… 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 adaptive COT control scheme that is concurrently very efficient at light-load …
