Abstract
In a voltage conversion circuit, a sampling signal and a triangular wave signal are synthesized into a first signal, and the first signal and a second signal are compared to output a pulse-width modulation (PWM) signal. A frequency of the PWM signal may be determined by a frequency of the triangular wave signal. Therefore, the frequency of the PWM signal is fixed using the frequency-fixed triangular wave signal. Turning on or switching off of a power transistor in a voltage conversion subcircuit is controlled according to the PWM signal to convert a received direct current input voltage into a direct current output voltage, thereby implementing a fixed operating frequency for the voltage conversion circuit.
