A reference voltage is connected to a second input of the comparator. Furthermore, the arrangement comprises a sequential logic, that is coupled to the output of the comparator that comprises a first output and a second output. A digitally controllable switch element for providing a superposition signal is connected to the output of the sequential logic and the first input of the comparator.

Abstract: A method includes a voltage converter outputting an output voltage that is based on an input voltage and on a first multiplication factor, determining a predicted current sink voltage based on a new multiplication factor obtained from a set of selectable values, based on a signal derived from the input voltage, based on a load voltage across an electrical load, and based on a correction voltage. The method also includes comparing a predicted current sink voltage with a predetermined threshold value and outputting the new multiplication factor to a control input of the voltage converter if the predicted current sink voltage exceeds the predetermined threshold value.

Abstract: An integrated circuit includes a comparator having a first input, a second input, and an output for providing a comparison result. The first input is connected to a readable component having a predefined value, and the second input is connected to a reference component. A control unit is at the output of the comparator. The control unit controls at least one function block based on the comparison result.

Abstract: A circuit arrangement (1) for voltage conversion comprises a forward branch (60) with a first load terminal (45) to which an electrical load (47) can be coupled and a feedback branch (61) with a sampling device (30). The electrical load (47) can be operated with pulse width modulation. A method for voltage conversion comprises the following steps: an electrical load (47) is supplied with energy using pulse width modulation. A feedback voltage (Vfb) that can be tapped at a terminal of the electrical load (47) is sampled in a first clock phase during which the electrical load (47) is supplied with energy. The voltage conversion is controlled as a function of the feedback voltage (Vfb).

Abstract: The invention specifies an arrangement with a voltage converter (1) for supplying power to an electrical load (2) having a current sink (3), a prediction unit (5) and a comparator (6) and also an associated method. The voltage converter (1) can be connected to a voltage source and drives a series circuit which comprises a means for connecting the electrical load (2) and the current sink (3). The voltage at the output of the voltage converter (1) has a dependency on a multiplication factor. The prediction unit (5) ascertains a predicted current sink voltage, that is to say the voltage dropping across the current sink, for a new multiplication factor. The comparator forwards the new multiplication factor to the voltage converter if the predicted current sink voltage is higher than a prescribeable threshold value. The arrangement described is particularly well suited to supplying power to light emitting diodes.

Abstract: According to the suggested principle, a comparator (9) is provided in an integrated circuit (1), which reads out an externally attachable component (4) and compares the value with the value of a reference component (6). The comparison result is forwarded to a control unit (12) which addresses at least one function block (13a, 13b) of the integrated circuit arrangement (1) depending on the comparison result. Accordingly, the mode of operation of the chip (1) is determined by the value (Rprog) of the externally attachable component (4) and/or is programmed thereby. The suggested principle is applicable, for example, with Power Management Units.
