  What is an LED driver?

 


  The LED driver changes the power supply to a specific voltage and current to drive the LED voltage converter. Generally speaking, the input of the LED driver includes high-voltage power frequency AC (ie, mains), low-voltage DC, high-voltage DC, and low-voltage and high-frequency AC (such as the output of electronic equipment). transformer). The output of the LED driving power supply is mostly a constant current source, and the voltage can be changed as the forward voltage drop of the LED changes. The core components of LED power supply include switching controller, inductor, switching element (MOSFET), feedback resistor, input filter, output filter, etc. According to the requirements of different occasions, there must be input overvoltage protection circuit, input undervoltage protection circuit, LED open circuit protection,
