Abstract:
A power-supply circuit may include a current generator configured to generate a regulated current. The current generator may include a switching stage, a current sensor, and a regulation circuit configured for driving the switching stage as a function of a feedback signal supplied by the current sensor. The power-supply circuit may further include an electronic switch configured to shortcircuit selectively the output of the current generator as a function of a drive signal, and a control circuit configured to generate the drive signal for opening or closing selectively the electronic switch. In particular, the current generator is configured to activate or de-activate generation of the regulated current as a function of an enable signal, and the control circuit is configured to generate the enable signal and the drive signal in such a way as to synchronize the ripple in the regulated current with the further drive signal.

Claim (Index 1):
A power supply circuit comprising:\n two output terminals for providing a current (i out ); a current generator configured to generate a regulated current (i L ), wherein said current generator comprises:\n a) a switching stage comprising one or more electronic switches and one or more inductors, said switching stage being configured to provide said regulated current as a function of one or more drive signals, \n b) a current sensor configured to detect at least one feedback signal indicative of said regulated current provided by said switching stage, and \n c) a regulator circuit configured to generate said one or more drive signals for said switching stage as a function of said at least one feedback signal; \n an electronic switch configured to selectively short circuit the output of said current generator as a function of a further drive signal; and a control circuit configured to generate said further drive signal for opening or closing selectively said electronic switch; characterized in that said current generator is configured to activate or deactivate the generation of said regulated current as a function of an enable signal, and said control circuit is configured to generate said enable signal and said further drive signal, in order to repeat periodically the following steps: a) after a first time-interval, activating said current generator; b) after a second time-interval, opening said electronic switch, c) after a third time-interval, closing said electronic switch, and d) after a fourth time-interval, deactivate said current generator.
