By a News Reporter-Staff News Editor at Journal of Engineering -- According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventors Massolini, Roberto Giampiero (Pavia, IT); Granato, Maurizio (Milan, IT); Frattini, Giovanni (Travaco' Siccomario (PV); IT), filed on December 30, 2015, was published online on February 14, 2017.

The assignee for this patent, patent number 9570992, is TEXAS INSTRUMENTS INCORPORATED (Dallas, TX).

Reporters obtained the following quote from the background information supplied by the inventors: "Power conversion circuits or power converters are used to convert input power to deliver output power to drive a load. Multiple output converters deliver two or more outputs, such as output voltage signals to drive separate loads, typically by converting power from a single input source or supply. In many applications, it is desirable to provide two or more isolated output voltages from a single converter. Line regulation is desirable to control the converter output voltages in the presence of potentially wide variation in the input supply voltage received by the converter, and thus it is often desirable to provide some form of regulation for both outputs. When one of the multiple outputs is isolated, namely the second, providing feedback for regulating the second converter output across an isolation barrier is impractical in many applications due to cost and/or size constraints."

In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "Disclosed examples include multiple output DC to DC converters with a buck converter including a half bridge switching circuit and transformer primary winding to provide a first output voltage signal, as well as a boost converter to provide an isolated second output voltage signal. The boost converter includes a transformer secondary winding magnetically coupled with the primary winding to provide a boost converter inductor, a switching circuit, an output diode providing the second output voltage signal, and a PWM controller that synchronizes the boost converter switching with the low side switch of the buck converter based on a sensed voltage of the transformer secondary winding."
