Patent ID: 8519916

Claim:
A system comprising: a power supply; a control switch formed on a substrate, the control switch including: a first terminal coupled to a first terminal of the supply and to a control drain finger, a second terminal coupled to a control source finger, the control source finger coupled to a load, and a third terminal coupled through a control gate pad to a control gate finger disposed between the control drain finger and the control source finger; a sync switch formed on the substrate, the sync switch including: a fourth terminal coupled to the second terminal of the supply and to a sync source finger, a sync drain finger contiguous with the control source finger to form a single continuous ohmic finger, a fifth terminal coupled through a sync gate pad to a sync gate finger disposed between the sync drain finger and the sync source finger, the control gate pad and the sync gate pad disposed between the control drain finger and the sync source finger; and a driver coupled to the third terminal of the control switch to provide a control gate signal to the control gate finger for switching current between the control drain and the control source, the driver coupled to the fifth terminal of the sync switch to provide a sync gate signal to the sync gate finger for switching current between the sync drain finger and the sync source finger.
