    Abstract: An intelligent multi-stage variable-power switch power supply device has an output of a bridge rectifier connected with the input of an EMI filter and the output of the EMI filter connected with a single chip through a standby topology and is connected with two or more different power topologies through different MOSFET switches respectively. The standby topology is connected with a load through a standby current sensor and a load detection circuit in turn and with the different power topologies being connected with loads through respective corresponding working current sensors. The output of standby current sensor, the outputs of the working current sensors and the output of the load detection circuit are connected with the input of the single chip respectively, while the output of the single chip is connected with the inputs of a plurality of MOSFET switches to control the on and off states of the different power topologies.
