Abstract
A COT (constant on-time) buck converter includes a first transistor, a second transistor, a driver circuit, an inductor, a first resistor, a second resistor, a capacitor, a load, and a feedback loop circuit. The feedback loop circuit includes a first switch, a second switch, an error amplifier, a comparator, a frequency locked loop circuit, an inverter and a COT logic circuit. The COT buck converter is able to improve DC (direct-current) regulation efficiency and transient response time.
