Product Description

NU510 is a medium power linear current regulation

component that can be easily used in various LED lighting

applications. It is equipped the excellent feature of good

load/line regulation capability, minimized chip current skew,

stable output current in high power or load voltage fluctuating

environment that can be used in wide area of LED lighting

source to maintain the uniformity of light intensity . NU510

also can be used in the digital PWM controlled circuit to

achieve more precise current adjusting in gray level

applications.

Current sink

A special cascade mode is also provided by NU510. In

high power supply voltage and low LED load dropout voltage

application, two or more NU510 can be connected in series to

share redundant high voltage. With the exclusive voltage

sharing technology of NUMEN tech., the extra redundant

voltage that exceeds the preset threshold voltage (Viboost) can

be shared by next NU510.

With the feature of wide power supply range design and

ultra low I_DDconsumption, the NU510 supports the self

powered structure in LED lighting applications. In this

structure, the NU510 no need to be provided a dedicate power

circuit even the system power voltage is much higher than the

maximum operation voltage of NU510. The V_DDpower can be

gotten from the proper position in LED series of system.
