A description is given of a switching voltage regulator control device. The regulator comprises at least a first (1) and a second (2) half-bridge each comprising at least one switch (11, 12, 21, 22); the first half-bridge is located between an input voltage (Vi) to the regulator and a reference voltage (GND) and the second half-bridge is located between an output voltage (Vo) from the regulator and the reference voltage (GND). The regulator comprises detecting means (31) suitable for detecting the error between a reference voltage (KVo) representative of the output voltage and another reference voltage (Vref) and integration means (32) suitable for integrating said error; the control device (100) has in input said input voltage (Vi) of the regulator. The control device (100) is suitable for providing a first duty cycle (Di) for driving the switches belonging to the first half-bridge (1) that is proportional to the value of the integrated error (e1) divided by the value of the input voltage (Vi) to the regulator and a second duty cycle (Do) for driving the switches belonging to the second half-bridge (2) that is proportional to the value of the input voltage (Vi) to the regulator divided by the value of the integrated error (e1).
