Abstract
A buck regulator circuit including an inductance is provided with an input current via a pass transistor and a second transistor disposed in drive relation to the pass transistor. The second transistor supplies current to the inductance at a tapped connection so the second transistor may drive the first transistor at a voltage level sufficiently high for saturating the first transistor.
