    600mA Buck Regulator LED Driver for 20W High Power LED 
     

     

    Overview:

    Welcome to use LED driver series by Sure Electronics. This product integrate a A6211 chip by Macroblock– a high efficiency, constant current and step-down DC/DC converter. Featuring under voltage lock out (UVLO),over temperature protection, LED open-circuited protection and LED short-circuited protection, A6211 makes the drivers’ application safer. Additionally, to ensure the system reliability, the A6211 builds thermal protection(TP) function inside. This function protects IC from overheating in various applications. Thus LED drivers shall serve for longer time.
