LED Drivers

An LED driver is an electrical device that regulates power to an LED or a string of LEDs. LED drivers are incorporated into many LED lighting products to provide electrical power as required. LED drivers can be broadly classified into off-line or DC-output drivers and on-line or AC-output drivers. Drivers usually employ a switching regulator to convert a voltage or current to the exact level required by the LED load.
