High frequency of LED switching power supply is the direction of its development. High frequency makes switching power supply miniaturized, and makes switching power supply enter a widerRead Article
The principle of switching power supply is to make the power transistor work under two working conditions: on-off and on-off. In other words, it is realized by chopping the amplitudeRead Article
LED switching power supply is a high-speed switch on and cut-off by the circuit to control the switch tube. It converts DC into high frequency AC to change the voltage of the converterRead Article
constant pressure function, can limit the highest value of output voltage, in the case of no load or light load, to ensure constant pressure voltage limit output, to ensure the safetyRead Article
Depending on the LED current and voltage characteristics, it is desirable to use a constant current drive. It avoids the change of the forward voltage of the LED and causes the current to changeRead Article
To achieve the purpose of illumination, the LED needs a forward voltage to allow current to flow. The LED driver therefore has to provide a forward bias to the LED to illuminate it.Read Article
