Abstract
The process for starting a power supply circuit which includes a switched-mode power supply is performed using: a first phase during which, if an output voltage of the switched-mode power supply is lower than a first voltage, the switched-mode power supply operates in pulse width modulation mode to increase its output voltage up to said first voltage; and when the output voltage has reached the first voltage, a second phase during which the switched-mode power supply operates in a bypass mode.
