Adjustable Constant Current

Regulator & LED Driver

45 V, 90 − 160 mA + 15%, 2.7 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. The CCR is based on

patent- pending 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.

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, which is lead-free RoHS

compliant and uses halogen- free molding compound. For the

AEC−Q101 part please see the NSI45090JD datasheet.
