Title: Switching power supply
Inventor: SASAKI MASATO
IPC: H02M3/335
Filed: 2000-05-09
Abstract: PROBLEM TO BE SOLVED: To provide a switching power supply which can continuously change the switching frequency and can maintain high efficiency even in the waiting load condition. SOLUTION: In a switching power supply in which a primary winding 3a of a transformer is switched with a switching element 4 and a voltage transferred to a secondary winding 3b of the transformer 3 is supplied to a load 9, a frequency variable circuit 21 is provided to continuously vary the switching frequency of the switching element 4 based on the condition of the load 9. This frequency variable circuit 21 increases a combined resistance at both ends of a resistor 15 as inversely proportional to the detected voltage from a load detecting circuit 20. As a result, the oscillation frequency of a PWM control circuit 6 is lowered and accordingly the switching frequency of the switching element 4 is lowered. The load detection circuit 20 detects a voltage which becomes smaller as the load 9 becomes small.
