Circuit arrangement and method for voltage conversion

摘要

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).
