Abstract
A power supply apparatus is provided. The power supply apparatus includes a first power pin, a second power pin, a DC output regulator, a current sensing circuit, and a compensation circuit. The first and second power pins are coupled to an external load through a first wire and a second wire respectively. The DC output regulator receives an input voltage and a feedback voltage and generates an output voltage and an output current. The current sensing circuit senses the output current and generates a sensing voltage. The compensation circuit generates a compensation voltage responding to the sensing voltage. The compensation voltage is a sum of a voltage drop on the first wire and a voltage drop on the second wire. The compensation circuit compensates the output voltage according to the compensation voltage, such that a load voltage of the external load is kept at a stable voltage value.
