Abstract: A transformer respectively includes a first isolation barrier, a first inductive element, a second isolation barrier, and a second inductive element. The first isolation barrier and second isolation barrier each comprise multiple isolation layers. The transformer also includes magnetic material including a top magnetic portion disposed above the first isolation barrier. The transformer also includes a bottom magnetic portion disposed below the second inductive element; The transformer further includes an intermediary magnetic portion extending from the top magnetic portion to the bottom magnetic portion via a through-hole within the first isolation barrier, first inductive element, second isolation barrier, and second inductive element. The transformer yet further includes at least one lateral magnetic portion extending from the top magnetic portion to the bottom magnetic portion. The at least one lateral magnetic portion is disposed laterally from the first isolation barrier, first inductive element, second isolation barrier, and second inductive element.

Abstract: 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.
