Abstract
Official abstract text for this publication.
According to one exemplary embodiment, a buck converter for converting a high voltage at an input of the buck converter to a low voltage at an output of the buck converter includes a III-nitride switch interposed between the input and the output of the buck converter and a low resistance switch interposed between the output of the buck converter and a ground. The buck converter further includes a control circuit configured to control a duty cycle of the III-nitride switch. The III-nitride switch has a sufficiently high switching speed so as to allow a ratio of the input high voltage to the output low voltage of the buck converter to be substantially greater than 10.
First claim
Opening claim text (preview).
The invention claimed is: 1. A buck converter for converting a high voltage at an input of said buck converter to a low voltage at an output of said buck converter, said buck converter comprising: a fast III-nitride switch interposed between said input and said output and a low resistance switch interposed between said output and a ground, wherein said fast III-nitride switch and said low resistance switch form a half-bridge directly coupled between said input of said buck convert…
