Abstract:
A DC-DC voltage converter has a pair of switching transistors to provide an output voltage and are alternately switched in a boost mode of operation responsive to control signals. An inductor is connected to the pair of switching transistor and has an inductor current flowing there through. A current sensor monitors an input current and generates a current sense signal responsive thereto. Control circuitry generates the control signals to the second pair of switching transistors responsive to the current sense signal, the output voltage and a current limit signal, wherein when the current limit signal indicates the inductor current exceeds a current limit the control signals configure the pair of switching transistors to decrease the inductor current.
