    • Provided is a semiconductor device capable of compensating for highly precisely current in a small circuit size. A first circuit operates in synchronization with a first clock (CLK1) having a first frequency, and generates N number of parallel data sets (D1-DN) for every cycle period of the first clock (CLK1). An interface circuit (20) time-division multiplexes the N number of data sets received from the first circuit (10). A second circuit (30) processes the N number of data set (D1-DN) thus time-division multiplexed, in synchronization with a second clock (CLK2) having a second frequency which is N times the first frequency. A determination unit (22) determines whether or not the N number of data sets are effective data which instructs a flip-flop group (32), which is configured as a state holding element included in the second circuit (30), to generate a substantial effective state transition. In a cycle period in which the N number of data sets are determined as being ineffective, a data substitution unit (24) replaces at least a portion of the N number of data sets with current compensation data (D_CMP).

    • The present invention relates to a switch control device, a power supply device including the same, and a driving method thereof. An AC input of the power supply device is connected to a rectifying circuit. The power supply device includes a power switch in which an input current passing through the rectifying circuit flows for an on-period and the switch control device which detects a half-on point that is the middle point of the on-period, calculates the input current by using the sampling result of a sensing voltage following the current which flows in the power switch for the on-period at the half-on point and the on-period, and controls the input current to follow a reference sinusoidal wave. The reference sinusoidal wave follows a sinusoidal wave obtained by fully rectifying the AC input. [Reference numerals] (200) Half-on detection unit;(300) Input current calculation unit
