Smart household application


Smart home controller pursues the beauty and miniaturization, the PCB must work reliably in small volume to achieve smart home’s convenient function, such as the curtain controller should has the function of remote control, panel display, scene control and so on.

City power goes into AC/DC converter after pass through the protective circuit. The 5Vout from the converter powers to the load include processor and relay and so on.

The scenario of switching power supply replacing transformer is based on the design of the parameters of the switching power supply, to output regulated voltage. In addition of its overcurrent protection and short current protection to achieve the features of simple peripheral current and PCB layout. As the switching power supply was controlled by high frequency, the transformer can be designed to very small and minimize the whole size, which finally make up the disadvantages of two methods above-mentioned.
