Description
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.
This driver features small size, high efficiency, stability, long service time and easy installation. LED dimming can be controlled via an extra pulse width modulation (PWM) through EN pin.
