<p>A control circuit (18) and method for regulating the current flow through a series connected inductor (20) and transistor (16). The circuit comprises an operational amplifier (34) for receiving a first voltage proportional to the current flow, for receiving a variable second voltage, and for providing a control current to the transistor (16) which keeps the transistor (16) out of its saturation region.</p> |
