Abstract

A circuit for DC-DC conversion with current limitation comprises a DC-DC converter (100) with a coil (110) and a controllable switch (120) that can be switched into a low-impedance and a high-impedance state, and a current limiter (300a, 300b) for generating a control signal (IOC) for controlling the state of the controllable switch in the DC-DC converter (100). The current limiter (300a, 300b) is constructed such that the current (IL) through the coil at which the current limitation takes place is nearly independent of the ratio of the on-times and off-times of the controllable switch in the DC-DC converter (100).
