Abstract
A constant on time converter control circuit and a constant on time converter are provided. The constant on time converter control circuit comprises an error amplifier, a voltage to current converter, and an initial current source. The error amplifier is for receiving a reference voltage signal and a feedback voltage signal and outputting a compensated voltage signal. The voltage to current converter receives the compensated voltage signal and outputs a converted current signal. The initial current source provides an initial current signal. The initial current signal and the converted current signal form a new reference voltage signal. A constant on time OFF time comparator receives the new reference voltage signal and the feedback voltage signal and outputs a control signal. The control signal affects the turning on and turning off of electronic switches to produce an output voltage of a constant on time converter.
