摘要： A multi-phase power converter with constant on-time control includes a plurality of channels to convert an input voltage into an output voltage, and each of the channels is driven by a control signal. When all channel currents of the channels are balanced, each of the control signals remains a constant on-time. When the channel currents are imbalanced, the on-times of the control signals are modulated according to the difference between each channel current and a target value for current balance between the channels.
