A power supply includes a transformer having a primary winding and one or more secondary windings. The power supply also includes a primary switch coupled to the primary winding, a control unit coupled to control the primary switch, and N output circuits each to provide a respective one of N output voltages. N is an integer greater than one. Each of the N output circuits also includes a feedback circuit to produce a respective feedback signal representative of the respective one of N output voltages to the control unit to regulate the respective one of N output voltages. The power supply also includes a switching arrangement coupled to the N output circuits. The switching arrangement is to selectively couple each of at least N−1 of the N output circuits to a respective one of the one or more secondary windings during a respective time period. The switching arrangement is to couple the respective feedback signal representative of the respective one of the N output voltages to the control unit during the respective time period.
