Abstract
An inductive current sensor is used for a constant peak current circuit of a DC-DC conversion apparatus and has a sampling unit, a voltage-voltage conversion unit and an input voltage compensation unit. The sampling unit is used to receive a feedback voltage and an input voltage and generate a sampling voltage proportional to the feedback voltage accordingly, and the feedback voltage is related and inversely proportional to an inductor current by the DC-DC conversion apparatus. The voltage-voltage conversion unit is electrically connected to the sampling unit to receive the sampling voltage and the input voltage, and generate a sensing voltage inversely proportional to the sampling voltage accordingly. The input voltage compensation unit is electrically connected to the voltage-voltage conversion unit for receiving the input voltage to provide an initial voltage level of the sensing voltage, and the initial voltage level is proportional to the input voltage.
