The development direction of switching power supply and LED drive power, do you know? Switching power supplies and LED driving power supplies are the two most widely used power supply types in the power industry. Today Xiaobian will tell you about the two types of power supply.


At present, switching power supplies are widely used in almost all electronic devices due to their small size, light weight and high efficiency. It is an indispensable power supply method for the rapid development of the electronic information industry. The switching power supply is defined according to its voltage regulation method, along with a linear power supply.

Switching power supply is a kind of power supply that uses modern power electronics technology to control the ratio of time when the switch is turned on and off, and maintains a stable output voltage. The switching power supply is generally composed of a pulse width modulation (PWM) control IC and a MOSFET. With the development and innovation of power electronics technology, switching power supply technology is constantly innovating.

The LED is actually a current-driven low-voltage unidirectional conductive device. The LED driver should have DC control, high efficiency, PWM dimming, overvoltage protection, load disconnection, small size, and ease of use.

The high frequency of LED drive power is the direction of its development. The high frequency makes the switching power supply miniaturized, and the switching power supply enters a wider range of applications, especially in the high-tech field, which promotes the miniaturization of high-tech products. Lightweight. In addition, the development and application of switching power supplies are of great significance in terms of energy conservation, resource conservation and environmental protection.
