Abstract
A power transistor and a power converter are disclosed that may improve the on-resistance and corresponding silicon area of a power transistor. The power transistor may comprise a drain, a source, and a channel therebetween divided into a plurality of transistor stripes, the plurality of transistor stripes being grouped in a plurality of different groups. The power transistor may further comprise a first top metal associated with one of the drain and the source, and a second top metal associated with the other of the drain and the source. The second top metal includes at least one portion that is coupled to different groups of transistor stripes. A related method for determining a layout topology of a power transistor is also disclosed.
