Abstract
A power supply capable of making soft start efficiently. A power supply (10) is such that the time lag from the soft start trigger representing the start of soft start control to the actual soft start can be decreased by offsetting the potential of a soft start signal from the ground potential. The offset is slightly lower than the minimum potential of a triangular signal. The highest potential level of the soft start signal is preferably lower than the power supply potential.
