Abstract: The present invention relates to a converter circuit and a conversion method for converting an input signal of a first value to an output signal of a second value based on a switched operating mode, wherein an output feedback loop (40) and an additional input forward control loop (60) are provided. The additional input forward control loop (60) serves to correctly control a switching parameter not only with respect to the output load but also over a wide input voltage range. This leads to an improved power efficiency and reliability of the converter circuit.

Abstract: A bus system (BS) for selectively controlling a plurality of identical slave circuits (slave A) comprises a bus (B) having a clock line (CLOCK) and at least one data line (DATA). The bus system (BS) includes at least one master circuit (1) and a plurality of slave circuits (2) with a group of identical slave circuits (slave A) connected to said bus (B). Each of the identical slave circuits (slave A) comprises an input-terminal (AD). The bus system (BS) further includes a selection circuit (3) connected to said bus (B), said selection circuit (3) is connected to each of said input-terminals (AD) for configuring at least one of the identical slave circuits (slave A) to be addressable by a master circuit (1) via said at least one data line (DATA).

Abstract: The present invention relates to a converter circuit and a conversion method for converting an input signal to an output signal of a predetermined value based on a switched operating mode, wherein a first control loop (40) is provided for comparing the predetermined value of the output signal to a first reference value and for generating a feedback signal in response to the comparison result; and wherein a second control loop (60) is provided for comparing a time period passed until the feedback signal is generated to a second reference value and for controlling the switching parameter of the switched operating mode in response to the comparison result. As a result, the output signal is correctly controlled not only with respect to the output load but also over a wide range of the input signal, so that power efficiency and reliability can be optimized.
