Abstract
A control circuit provides a control signal for a constant on-time PWM switching converter to produce an output voltage, such that the converter operates with a constant on-time at a first state and operates with a variable on-time at a second state, so as to decrease the switching frequency and thereby the switching loss, to increase the efficiency of the converter, to improve the transient response, and to reduce the recovery time of the output voltage.
