ABSTRACT:
A semiconductor device has a DC-DC converter control circuit for selectively carrying out a boosting operation and a deboosting operation in accordance with a value of a power supply voltage supplied to the DC-DC converter control circuit and for outputting an activation pulse during a rise of the power supply voltage. The DC-DC converter control circuit has a voltage detection circuit for monitoring the power supply voltage to judge whether the DC-DC converter control circuit carries out the boosting operation or the deboosting operation. A control circuit controls the output of the activation pulse in accordance with an output signal from the voltage detection circuit and stops the output of the activation pulse when the voltage detection circuit judges that the DC-DC converter control circuit carries out the deboosting operation.
