ABSTRACT:
A control circuit for controlling an output voltage of a DC--DC converter which supplies power to various semiconductor device, such as a processor and a memory, by way of an output transistor. The control circuit drives the output transistor in response to an external control signal. The control circuit gradually reduces an operating time of the output transistor by performing a discharge operation in response to the external control signal being inactive.
