An integrated circuit controller for controlling the operation of a voltage converter which includes a first comparator for comparing a voltage associated with an input of a boost converter with a threshold voltage and generating a control signal in response thereto. A second comparator compares a second voltage associated with an output of the boost converter with the threshold voltage and generates a second control signal in response thereto. Driver circuitry generates a first switching transistor drive signal and a second switching transistor drive signal. The first switching transistor drive signal is used for driving an upper gate switching transistor of a buck converter. The second switching transistor drive signal may be configured in a first mode of operation to drive a lower gate switching transistor of the buck converter and may be configured in a second mode of operation to drive a switching transistor of the boost converter. Control logic enables/disables at least a portion of the driver circuitry responsive to the control signal and the second control signal.
