Abstract
There is provided a switching power supply circuit () for supplying a power supply voltage to a load through a transmission line PL. The switching power supply circuit () includes: a voltage conversion unit () for inputting thereinto an input voltage VIN and a control signal Vc, converting the input voltage VIN into an output voltage Vo having a magnitude corresponding to the control signal Vc, and outputting the output voltage Vo to the transmission line PL; a signal generation unit () for monitoring a load current ILOAD flowing through the transmission line PL and generating a signal corresponding to a voltage dropped in the transmission line PL; and a low pass filter () for outputting the signal generated in the signal generation unit () to the voltage conversion unit () as the control signal Vc.
