Buck converter with multiple outputs and method of operation thereof
First Claim
1. A buck converter with multiple outputs including a primary output and at least one auxiliary output, comprising:
- a transformer having a primary winding and at least one secondary winding;
a switch, coupled to said primary winding, configured to impress an input voltage across said transformer, a first DC output voltage configured to be provided at said primary output employing a magnetizing inductance associated with said transformer as an inductor; and
an output inductor coupled to said at least one secondary winding, a second DC output voltage configured to be provided at said auxiliary output via said output inductor.

Abstract
A multiple output converter, and related method of operation thereof, that includes a primary output and at least one auxiliary output. In one embodiment, the multiple output converter includes a transformer having a primary winding and at least one secondary winding. The multiple output converter also includes a switch, coupled to the primary winding, that impresses an input voltage across the transformer. A first output voltage of the multiple output converter is produced at the primary output via a magnetizing inductance associated with the transformer. The multiple output converter still further includes an output inductor coupled to the at least one secondary winding. A second output voltage of the multiple output converter is produced at the auxiliary output via the output inductor.
