Abstract
A current sensing module and a power conversion apparatus and an electronic apparatus using the same are provided. The current sensing module is suitable for detecting a first load current flowing through a first load. The current sensing module includes a sampling stage circuit and an output stage circuit. The sampling stage circuit couples across the first load and selectively exchanges coupling nodes between the sampling stage circuit and the first load by a multiplex switching means, so as to sample the first load current flowing along a first direction or a second direction, and thus generate a sampling signal. The output stage circuit is coupled to the sampling stage circuit and switches coupling nodes between the output stage circuit and the output terminal of the sampling stage circuit, so as to generate a current indication signal indicating the magnitude of the first load current according to the sampling signal.
