Abstract
Compared with a pulse-width modulated voltage-mode controlled switching converter, a constant on-time (COT) controlled switching converter has extensive industry application due to its fast transient response. However, the conventional COT controlled switching converter has poor output-regulation accuracy. A new control method that provides both fast transient response and high output-regulation accuracy for switching converters, called dual COT control, is proposed. The analysis results are verified by circuit simulation.
