SMPS stands for Enclosure Power Supply. They are used in many places in PC. In a modern PC, Enclosure Power Supply that takes rectified AC input from the wall,performs power factor correction & converts the output into one or more lower voltage DC outputs. power supply driver for led strip light is applied in projects.

Compared with traditional linear power supply, SMPS provides higher efficiency and space saving, but attention must be paid to ensure that the output noise is very low.

Whether on or off, therefore very little energy consumption as heat and very high efficiency levels can be achieved.Due to the high efficiency and low heat dissipation level, the power supply for led can be made more compact.One of the things that makes switching mode power supplies so attractive is cost. The higher efficiency and switching characteristics of the design mean that the amount of heat needed to be reduced is lower than that of the linear power supply, thus reducing the cost. The switching nature of strip led power supply has long meant that many components cost less.Switching power supply technology can be used to provide efficient voltage conversion in voltage boost or "boost" applications or buck applications.
