| 摘要 |
The invention relates to an electronic device and a method for DC-DC-conversion. The electronic device includes energizing switch and a commutating switch coupled at a switching node. The switching node is configured to be coupled to an inductor. The electronic device is configured to repeatedly suspend the regular synchronous switching of the commutating switch during a load detection period, to sense the voltage at the output node during the load detection period and to determine a high-load condition or a light-load condition of the DC-DC-conversion based on the sensed voltage at the output node.
