<p>A switching power supply is provided with a first switch (SW1) arranged between nodes (N21, N31), a second switch (SW2) installed between nodes (N11, N22), a capacitor (C1) disposed between the second switch and the node (N22), a third switch (SW3) arranged between the nodes (N21, N12), a delay circuit (L1) which is disposed between the third switch (SW3) and the node (N12) and delays current for charging the capacitor (C1) and a first diode (D1) arranged between the nodes (N13, N22). In the first diode (D1), a node (N13)-side is a cathode.</p> |
