Abstract
A DC-DC converter includes a voltage converting block that converts an input supply voltage to an output voltage and includes a power switch turning on at on-time of a power driving signal, a power driving block that generates the power driving signal using an oscillation output signal, wherein a cycle of the power driving signal varies according to a cycle of the oscillation output signal and a length of the on-time of the power driving signal is fixed to a power time regardless of variation of the cycle of the oscillation output signal, a voltage-controlled oscillating block that generates the oscillation output signal, the cycle of which is controlled according to a level of an oscillation control signal, and a target tracking block that generates a feedback voltage and controls the level of the oscillation control signal such that a feedback voltage follows a target reference voltage.
