Patent attributes
A DC-to-DC converter comprising an input inductor which is connected to an input terminal, an output inductor which is connected to an output terminal, a capacitor which is connected in series with and between the inductors, a switch element which is connected via a first resistor to a common input/output conductor and to a first node that is common to the input inductor and the capacitor, and a diode which is connected via a second resistor to the common input/output conductor and to a second node that is common to the output inductor and the capacitor, the switch element being responsive to a switch control signal (Vsw) applied thereto for alternately making the switch element conducting and non-conducting such that currents flowing through the inductors flow through the switch element or through the diode during an on-interval and an off-interval of the switch control signal (Vsw), respectively, a control circuit having at least one measurement input for receiving a current measurement voltage (Vx) across the first and second resistors, a reference input for receiving a reference signal (Vref), and an output for supplying the switch control signal (Vsw).
