Abstract
A smoothing circuit for a switching power supply is formed of a combination of a reactor and a capacitor having a small equivalent internal resistance, and a MOSFET connected in series to the capacitor. The MOSFET is turned on by an output voltage of the smoothing circuit and has an ON-state resistance compensating for an equivalent internal resistance of the capacitor.
