Claims

[Scope of utility model registration request]

It has a transistor that turns on and off the current flowing through the primary winding of the transformer, and the first current output from the feedback winding of the transformer is directly applied to the voltage of the primary winding, feedback winding, or secondary winding when the transistor is off. The first current is applied to the transistor by shunting the second current through a shunt path consisting of a capacitor that stores charge in response to the current or indirectly, and a Zener diode connected in series with the capacitor.
A ringing chain type DC configured to control the base current, which is the difference between the current and the second current.
A ringing chain type DC-DC converter, characterized in that the capacitor has a characteristic such that the impedance value at low temperature at the switching frequency is several times or less the value at room temperature.
