NSIC2050JBT3G
Constant Current Regulator
& LED Driver for A/C off-line
Applications
120 V, 50 mA + 15%, 3 W Package
The linear constant current regulator (CCR) is a simple, economical
and robust device designed to provide a costâeffective solution for
regulating current in LEDs (similar to Constant Current Diode, CCD).
The CCR is based on SelfâBiased Transistor (SBT) technology and
regulates current over a wide voltage range. It is designed with a
negative temperature coefficient to protect LEDs from thermal
runaway at extreme voltages and currents.
The CCR turns on immediately and is at 20% of regulation with
only 0.5 V Vak. It requires no external components allowing it to be
designed as a high or lowâside regulator.
The 120 V anodeâcathode voltage rating is designed to withstand
the high peak voltage incurred in A/C offline applications. The high
anodeâcathode voltage rating withstands surges common in
Automotive, Industrial and Commercial Signage applications.
