Being applied to a multi-channel switching voltage converter, an oscillating signal generation circuit includes a rectangular wave oscillator, two frequency dividing units, and four oscillators. The rectangular wave oscillator generates a pair of fundamental rectangular waves having an identical fundamental frequency but 180 degrees out of phase with respect to each other. In response to the pair of fundamental rectangular waves, the two frequency dividing units generate two pairs of auxiliary rectangular waves, each pair having an identical auxiliary frequency but 180 degrees out of phase with respect to each other. The auxiliary frequency is equal to a half of the fundamental frequency. In response to the two pairs of auxiliary rectangular waves, the four oscillators generate four oscillating signals wherein each valley of the oscillating signals is triggered by an edge of the auxiliary rectangular waves.
