Abstract
A synchronous buck direct current to direct current (DC-DC) converter includes a signal output terminal, an output stage circuit, a first comparator, a latch, a control logic circuit, a driver circuit and an on-time control circuit. The output stage circuit provides an output voltage to the signal output terminal according to an input voltage. The first comparator receives a reference voltage and a feedback signal related to the output voltage and outputs a control signal. The latch receives the control signal and a timing signal and outputs an on-enable signal. The control logic circuit receives the on-enable signal and outputs an on-control signal. The driver circuit controls charge/discharge time of the output stage circuit according to the on-control signal. The on-time control circuit receives the on-control signal and the input voltage and outputs the timing signal related to a duty cycle of the output stage circuit.
