A constant on time control circuit, configured to control a converting circuit to transform an input voltage into a stable output voltage, is disclosed. The constant on time control circuit comprises a comparing circuit and a logic circuit. The comparing circuit compares a reference signal and a ...
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...
1 Introduction There are varieties of control techniques used for buck converters. These control approaches consist of voltage mode, current mode, hysteretic mode, constant on-time mode, constant off time mode, and adaptive on-time mode (D-CAP? mode). Both voltage mode and current mode require...
