Brief Introduction:

As the fourth member of the new LED driver series, this item consists of two small drivers fixed in a tailored converter, which is also used to for connection with power supply and LEDs, to output power up to 10W. The MBI6651chip by Macroblock is integrated (MSOP-8L-118mil) on each driver as the new step-down DC-DC converter. It is a high efficient chip which is designed to deliver constant current to light up high power LED. Features of MBI6651 help make its applications safer, such as UVLO (under voltage lock out), over temperature protection, LED open-circuited protection and LED short-circuited protection. Moreover, thermal protection (TP) function has been introduced to protect IC from overheating (165°C) in various applications.
