Abstract
A cable drop compensation circuit includes a current detection circuit, a compensation judgment circuit, and a compensation circuit. The current detection circuit detects a load current supplied to a load by a DC output circuit, so as to generate a current detection signal. The compensation judgment circuit receives the current detection signal, and generates a judgment signal when judging the load current higher than a predetermined compensation value. When receiving the judgment signal, the compensation circuit generates a compensation signal. In response to the compensation signal, the DC output circuit raises an output voltage by a compensation voltage.
