Abstract: A voltage boost device includes a first boost stage (4) and a second boost stage (5) connected to an input terminal and to an output terminal (10), the output terminal (10) supplying an output voltage higher than a supply voltage. The input terminal receives an operating condition signal (SB) having a first logic level representative of a standby operating state and a second logic level representative of an active operation state. The first boost stage (4) is enabled in presence of the second logic level of the operating condition signal (SB), and is disabled in presence of the first logic level of the operating condition signal (SB); the second boost stage (5) is controlled in a first operating condition in presence of the first logic level of the operating condition signal (SB), and is controlled in a second operating condition in presence of the second logic level of the operating condition signal (SB).
