Electronic circuit and buck converter including the electronic circuit

An electronic circuit, comprising:

• a first transistor device, a second transistor device, and a third transistor device, each comprising a control node and a load path;
• and
• a drive circuit,
• wherein the load paths of the first and second transistor devices are connected in parallel,
• wherein the load path of the third transistor device is connected in series with the load paths of the first and second transistor devices,
• wherein the first transistor device and the second transistor device are integrated in a common semiconductor body,
• wherein the drive circuit is configured, based on a control signal, to successively switch on the first transistor device and the second transistor device, so that the second transistor device is switched on after the first transistor device has been switched on,
• wherein the first and second transistor devices are integrated in a first semiconductor die,
• wherein the first semiconductor die includes the common semiconductor body, a first gate pad, a second gate pad, at least one first gate runner, at least one second gate runner, and a plurality of source metallizations,
• wherein the first gate pad forms a gate node of the first transistor device or is connected to the gate node of the first transistor device,
