PCT No. PCT/EP95/00163 Sec. 371 Date Jul. 18, 1996 Sec. 102(e) Date Jul. 18, 1996 PCT Filed Jan. 17, 1995 PCT Pub. No. WO95/20261 PCT Pub. Date Jul. 27, 1995Flyback converter has a regulating arrangement which is connected to an output and whose duty ratio is limited to a predetermined upper limit. A series circuit has a diode and an RC series circuit is connected to the rectifier diode of the main circuit (3) on the secondary side in order to supply the regulating arrangement with an auxiliary voltage which is greater than the output voltage. A further diode (44) leads from the series circuit to an output (a) of the auxiliary circuit (4). The flyback converter is suitable in particular for supplying ASICs, which require a relatively low supply voltage.
