NSI45035JZ, NSV45035JZ
Adjustable Constant Current
Regulator & LED Driver
45 V, 35 − 70 mA + 15%, 1.5 W Package
The adjustable constant current regulator (CCR) is a simple,
economical and robust device designed to provide a cost effective
solution for regulating current in LEDs (similar to Constant Current
Diode, CCD). The CCR is based on Self-Biased 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. The R_adj pin allows I_reg(SS) to be adjusted to higher
currents by attaching a resistor between R_adj (Pin 3) and the Cathode
(Pin 4). The R_adj pin can also be left open (No Connect) if no
adjustment is required. It requires no external components allowing it
to be designed as a high or low−side regulator. The high anode-
cathode voltage rating withstands surges common in Automotive,
Industrial and Commercial Signage applications. This device is
available in a thermally robust package and is qualified to stringent
AEC−Q101 standard, which is lead-free RoHS compliant and uses
halogen-free molding compound, and UL94−V0 certified.
