DESCRIPTION
When the power supply voltage is changed or fluctuating, the output current still remains unchanged. With this dedicate designed function, the VDD power can be derived easily from the whole lighting system. The output current of NU511 is set by an external resistor. While in full current output, the NU511 only need about 0.6V drop on output channel. The minimized voltage drop will increase the working range that limited by LED forward voltage variation in lighting system, to enhance the system efficiency and lower the heat generation from NU511.
