Adjustable Constant Current Regulator & LED Driver 45 V, 90 - 160 m A + 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 (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 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 ponents allowing it to be designed as a high or low- side regulator. The high anodecathode voltage rating withstands surges mon in Automotive, Industrial and mercial Signage applications. This device is available in a thermally robust package and is qualified to stringent AEC- Q101 standard, which is lead-free Ro HS pliant and uses halogen-free molding pound, and UL94- V0 certified.
