The significance of low power consumption in electronic products

Low power consumption is actually not a term unique to the embedded industry, for most of our common electrical appliances, such as. TVs, refrigerators, air conditioners, etc., all have the concept of low power consumption, including mobile phones and computers. Now let me tell you about science, in fact, low power consumption is not far from us, what does it mean for industrial production and embedded? Модуль питания

Household appliances, such as TVs, can be turned on and off through the remote control panel. This means that the TV has entered a low-power state, and only the necessary relevant functions are retained, and other functions that are not needed for the time being are involved. All peripherals are turned off. For TVs, the most power-consuming part of the screen is turned off, the main board of the processor is powered off, and only the MCU that monitors the infrared signal and the power supply of the circuit is kept, and the power consumption of the device is minimized to save energy.

Mobile phones, it is more sophisticated. The low power consumption of mobile phones is already a huge system. Everyone may find that when using mobile phones to play games, the mobile phone generates the most heat and consumes the fastest power. Caused by the power consumption control system. When the mobile phone is off, the mobile phone will only keep the internal core timer running and the signal detection of the power button part to ensure that the device can be started normally from the off state and the internal time will not be confused.

When the mobile phone is in normal use, for example, you take the mobile phone to refresh the news, the phone is actually in a relatively low power consumption mode, because the news does not put too much pressure on the CPU operation, and the refresh of the network and the screen also There is not too much pressure, so especially for the CPU, it will run at a controlled frequency, and it will not be fully loaded, and the corresponding network RF part and screen power supply part will not have too much pressure, and when you turn off the screen of the phone, then Naturally, the screen part will be set to the lowest power consumption, only the wake-up current will be reserved, the MCU frequency will be reduced to a very low level, and the network part will also be reduced in frequency accordingly, so that the network message push can still be received normally, but the power consumption of each part of the function is controlled to a very low level.

In the end, of course, when you are playing games with the most ideal full load, the screen is refreshed quickly, and the CPU and network RF parts are running at full speed. At this time, the mobile phone is actually running at full speed. At other times, it is in a state of relatively low power consumption.
