A power supply controller which is configured to mainly control a switching power supply configured to generate an output voltage from an input voltage by driving an inductor current flowing through an inductor by switching a half-bridge output stage at a predetermined switching cycle, the power supply controller includes: a sample-and-hold circuit configured to generate a current feedback signal by sampling and holding the inductor current flowing through an upper switch element, which forms the half-bridge output stage, during an on period of the upper switch element; and a feedback control circuit configured to, based on the current feedback signal sampled and held in a certain switching cycle among switching cycles of the upper switch element that are repeated at the predetermined switching cycle, control a duty of the upper switch element in a subsequent switching cycle.
