Abstract
PURPOSE:To reduce the size and simplify the circuitry by performing the primary side switching control through first secondary side output circuit while performing the independent phase control of second secondry output circuit during the switching on interval determined by the first secondary side output circuit. CONSTITUTION:When obtaining a plurality of stabilized outputs VOA, VOB from single non-stabilized power source Vin, the output voltage VOA from one output circuit 101A is stabilized by controlling the on-off ratio of the primary switching circuit 103 in accordance with said output voltage. While the output voltage VOB from the other output circuit is stabilized such that the secondary switching circuit 302 provided in each circuit follows to the on, off of said primary switching circuit to perform the phase control independently during on-interval.
