ABSTRACT:
A controller is provided for DC-DC converters of the type associated with a half-bridge driving stage of at least one inductive load, with a pair of power MOS transistors in Highside and Lowside configuration being driven by a corresponding converter. The controller includes an input for connection to a terminal of the inductive load. The controller also includes a read block for reading an inductive load phase current at the terminal, an over current comparator having a first input coupled to an output of the read block, and a bypass compensation network including an error amplifier block having a first input coupled to the terminal through a voltage divider, and a second input coupled to a reference potential. The compensation network has an output that is coupled to a second input of the over current comparator, and an output of the over current comparator is supplied to the DC-DC converter.
