com Adjustable Constant Current Regulator & LED Driver 50 V, 150 − 350 mA + 10%, 4.
2 W Package NSI50150ADT4G 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.
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 14% of regulation with only 0.
5 V Vak.
The Radj pin allows Ireg(SS) to be adjusted to higher currents by attaching a resistor between Radj (Pin 3) and the Cathode (Pin 4).
The Radj 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 anodecathode voltage rating withstands surges common in Automotive, Indu...
