摘要： A voltage converter connectable to a power source (PS) and a load (LD) provides a regulated output voltage (Vout) from a voltage (Vin) power source by switchable current paths including an inductive element (L). The voltage converter includes a plurality of switching elements for switching the current paths of the voltage converter as a forward-phase current path when the input voltage corresponds to the output voltage, as an up-phase current path when the input voltage is lower than the output voltage, and as a down-phase current path when the input voltage is higher than the output voltage. A central controller controls a switching state of the plurality of switching elements, a current sensing unit including a comparator for sensing a current flowing through at least one of the switching elements, and a plurality of processing units for processing the current sensing.
