Abstract
An integrated control and regulation circuit for a power stage of a regulated power supply, includes a current generator which, when the power supply is switched on, charges a decoupling capacitor to decouple a power stage of the power supply, through a first switch. The output from a logic circuit controls this first switch, and opens it when the regulated output voltage from the power stage reaches its nominal value. Preferably, a second switch controlled by the same output from the logic circuit deactivates a regulation loop of the power stage during the start up phase and in the case of a short circuit.
