Product Description

The NU511 is a single channel, open drain, linear

constant current LED driver. With up to 1.2A driving

current and maximum 1Mhz PWM dimming control support,

NU511 can be used for 0.5W to 3W high power LED string

in general or architecture decoration lighting applications.

Terminal Description

The capability of wide power supply range makes

NU511 work stably in uncertain power supply applications.

When the power supply voltage is changed or fluctuating,

the output current still remain unchanged. With this dedicate

designed function, the V_DDpower can be derived easily from

the whole lighting system.

Power

Output enable

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.
