What is SMPS?
Switching-Mode (or Switched-Mode) Power Supply refers to that class of devices that use a switching transistor (along with other components) to convert AC current into DC current of different voltages. The switching transistor is used since the mode of operation— constantly switching off and on, effectively “chopping up” the input power—is the most power-efficient. Using the same mechanism as in adapters for single devices would result in significant loss of energy as heat during the conversion process.
