タのベース端子との間に過電流防止手段を設けたことを
特徴とするＤＣ−ＤＣコンバータ。A voltage applied to the primary winding of the transformer via the tti switch is controlled intermittently by a switching transistor to obtain an output from the secondary winding of the transformer, and the output is compared with a reference voltage; In the ringing choke type DC-DC converter that controls the switching transistor based on the comparison result to obtain a stable output, an overcurrent prevention means is provided between the power switch and the base terminal of the switching transistor. Characteristic DC-DC converter.
