The power chip is mainly a chip in the electronic equipment system that takes on the transformation, distribution and detection of electric energy and other electric energy management responsibilities. It has dual in-line chips, and some chips are surface mount packages. It is mainly Responsible for converting source voltage and current into power that can be used by loads such as microprocessors, sensors, etc.

 The main functions of the power chip are as follows. The first point: The core of electronic equipment is mainly a semiconductor chip. In order to increase the density of the circuit, the feature size of the chip is getting smaller and smaller, and the electron intensity will decrease with the distance, which will increase linearly. Therefore, the difference Different electronic systems have different requirements on the power supply voltage, which means that different step-down power supplies are required. The second point: there are still many electronic product systems on the market now, all of which require a power supply higher than the power supply voltage, like the LCD TV at home, the backlight power supply behind the LCD monitor is the power chip, and there are ordinary white light LEDs Drivers, etc., all of which need to boost the system power supply, so a boost power supply must be used. The last point is that with the rapid development of modern technology, the requirements for electronic systems are getting higher and higher, so try to avoid all factors that interfere with the performance of electronic equipment. Therefore, a power supply with advantages in terms of noise and ripple can filter and stabilize the system power supply.

 All in all, the above is the function of the power chip.
