Description

The MBI6650 is a constant current power LED driver specially designed for applications using high power LEDs.The MBI6650 offers low quiescent current and high efficient operation ranging from a few milliamps up to 1.2A.Output current can be programmed by an external resistor.

Additionally, to ensure the system reliability, the MBI6650 is built with the thermal protection (TP) function and a thermal pad. The TP function protects IC from over temperature (140°C). Also, the thermal pad enhances the power dissipation. As a result, a large amount of current can be handled safely in one package.
