| 摘要 |
The invention relates to a circuit for converting DC voltage with current limitation, comprising a DC-to-DC converter (100) having a coil (110) and a controllable switch (120), which can be switched to a low-resistance state and to a high-resistance state, and a current limiter (300a, 300b) for producing a control signal (Ioc) for controlling the state of the controllable switch of the DC-to-DC converter (100). The current limiter (300a, 300b) is designed in such a way that the current (IL) through the coil at which the current limitation occurs is nearly independent of the relationship of the switch-on/switch-off times of the controllable switch of the DC-to-DC converter (100). |
