Abstract
A converter for feeding a load via an inductor with a current having a controlled intensity between a maximum level and a minimum level may include: a switch switchable on and off to permit or prevent, respectively, feeding of current towards said inductor; first and second current sensors sensitive to the current flowing through said switch when said switch is on or off, respectively; comparator circuitry to identify if the current intensity detected by said first current sensor and said second current sensor reaches said maximum level and said minimum level, respectively, by generating respective logical signals; and drive circuitry for said switch sensitive to said logical signals and configured to turn off said switch when the current intensity detected by said first sensor reaches said maximum level and turning on said switch when the current intensity detected by said second current sensor reaches said minimum level.
