| 主权项 | 1. A controlling method for a switching mode DC/DC converter, comprising a step of, when a detected value of an output voltage of the converter is not larger than a first predetermined value, causing a switching frequency of the converter to be operated at a rated value multiplied by a second predetermined value to curb at least one of an inrush current and an overshoot voltage generated by the converter during a soft-start thereof, wherein the first predetermined value is a rated output value of the detected value multiplied by a first rate, and both the first rate and the second predetermined value are no larger than 0.75. | ||
