Abstract:
A buck converter includes a first transistor, a second transistor, an inductor and a capacitor. The first transistor, the second transistor and the inductor are coupled to a switching node. A method includes charging the switching node for a predetermined duration using a first charging current, detecting a voltage at the switching node to obtain a first detection voltage, and determining the connection status of the inductor according to at least the first detection voltage.
