NSIC2020JB: Constant Current Regulator & LED Driver for A/C off-line Applications, 120 V, 20 mA ±15%

The linear 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 45% of regulation with only 0.5 V Vak. It requires no external components allowing it to be designed as a high or low-side regulator. The 120 V anode-cathode voltage rating is designed to withstand the high peak voltage incurred in A/C offline applications. The high anode-cathode voltage rating withstands surges common in Automotive, Industrial and Commercial Signage applications.
