ABSTRACT:
An electronic circuit combines a synchronous switching regulator circuit with an overvoltage detection circuit. The overvoltage detection circuit is configured to generate an overvoltage signal capable of an overvoltage state indicative of a power supply voltage being above a predetermined threshold voltage. The switching regulator circuit is coupled to receive the overvoltage signal. The switching regulator is also configured, in response to the overvoltage signal being in the overvoltage state, to generate a first control signal resulting in at least one of two series coupled transistors being in an off condition.
