タの保護回路。 A DC input power source, the primary winding of a transformer, and a switching transistor are connected in series to form a closed circuit, and the energy transferred to the secondary winding of the transformer by chopping the switching transistor is rectified to generate DC current. A switching regulator that obtains an output has an auxiliary winding on the secondary side of the transformer that adds a voltage to the secondary winding, and a rectified output of the addition output of the secondary winding and the auxiliary winding. A protection circuit for a switching regulator, characterized in that it compares two DC outputs and stops oscillation of the switching transistor when the output difference exceeds a certain value.
