摘要：A switching DC-to-DC converter includes multiple power supply channels,coupled in parallel between a DC voltage source and ground, for converting the DC
voltage source into multiple DC output voltages that are separate from each other. Anoscillator outputs multiple oscillating signals to render each of the multiple powersupply channels make at least one switching transition differently in the time domainfrom others of the multiple power supply channels, thereby improving transient noise.The multiple oscillating signals include two triangular wave signals with a phasedifference of 180 degrees and two pulse wave signals with a-phase difference of 180degrees. Rising edges of the two pulse wave signals occur simultaneously with either apeak or a valley of the two triangular wave signals, respectively.
