Abstract: The limiting circuit comprises a comparator (B), which makes the comparison between the output voltage (Vc) of the power device (T5, T6) and a predetermined reference voltage (Vrif). In the case wherein the output voltage (Vc) is just below the reference voltage (Vrif) the comparator (B) supplies a current to the load (L) suitable for preventing the output voltage from falling further below said reference voltage (Vrif).
