Method for controlling the voltage at the main output of a low power switched power converter in which is generated a first signal (14), representative of the voltage at an auxiliary output which is an image of the main output voltage; it is combined with a second signal (16), representative of an input current to the converter, for generating a first control signal which together with a first reference signal are applied to a first controller means, generating a second control signal. The second control signal together with a second signal coming from an oscillator means are applied to a comparator, generating a switching signal (17) for opening and closing the switching element (6), and consequently the voltage at the main output is regulated.
