Product Description

NU513 is a medium/high power linear current regulation

component that can be easily used in various LED lighting

applications. It has good load/line regulation characteristic,

minimized chip current skew, stable output current in high power

or load voltage fluctuating environment. Thus NU513 can be

used in large dimension LED lighting source that has good

lighting uniformity. NU513 also can be used in the digital PWM

controlled circuit to achieve more precise current adjusting in

gray level applications.

With the feature of wide power supply range design and

ultra-low IDD consumption, the NU513 supports the self-powered

structure in LED lighting applications. In this structure, the

NU513 no need to be provided a dedicate power circuit even the

system power voltage is much higher than the maximum

operation voltage of NU513. The VDD power can be gotten from

the proper position in LED streams of the system.

Applications

 General LED lighting

 Decoration lighting for architecture

 LED torch / flash light

 RGB lighting

 RGB display / indicator
