Abstract
A switching regulator power supply has multiple regulated and isolated voltage outputs. This is accomplished without the use of separate voltage regulators for each output voltage or extra transformer windings in the input circuitry of the power supply. Instead of an inductor, the primary winding of a transformer is used as the inductive component required in switching type regulators and is connected in series with the first output voltage. The secondary winding provides an isolated second output voltage. The primary to secondary turns ratio of the transformer determines the magnitude of the voltage.
