Abstract
A switching control circuit has a detector to detect a difference between a control object signal of a switching element to drive a load and a target signal of the control object signal, and gate adjustment circuitry to search for the timing at which the difference becomes the smallest by sweeping timing of adjustment of a gate signal of the switching element.
