Image gallery - 1 of 10. Depending on the types of technique used in a DC-DC converter, LED power supplies fall into two broad categories: switched mode power supply (SMPS) and linear power supply. What Is a Switching Power Supply? An LED switching power supply is an LED driver that uses a switching regulator as its DC-DC converter. LED drivers and LED power supplies are nearly interchangeable terms in LED lighting. In fact, LED driven switching power supply is also a power transformer, because it has many characteristics of the power transformer; The difference is that LED driven switching Linear regulators use linear, non-switching techniques to regulate the voltage output from the power supply. Picture Information. All linear regulators require an input voltage at least some minimum amount higher than the desired output voltage. Such power supplies are used for LED strips and 12V LED lamps.

The LED driver circuit is divided into constant-voltage type and constant-current type according to the power supply to the LED. But a common or garden 12v 1A supply LED drivers that use high-voltage AC power are called Off-Line drivers, or AC LED drivers. In most applications using a low voltage DC input LED driver is recommended. Even if your input is high voltage AC, using an additional switching power supply will make it possible to use a DC input driver. An electrical circuit that regulates the incoming power to provide a constant-voltage output has typically been referred to as a power supply, whereas an LED driver in the strict sense refers to an electrical circuit that provides a constant current output. A constant voltage driver could be a switch mode or linear supply. Depending on the types of technique used in a DC-DC converter, LED power supplies fall into two broad categories: switched mode power supply (SMPS) and linear power supply. 2 18 LED matrix driver with 8-bit analog and 8-/16-bit PWM dimming.
