Product Description

The NSI45025AT1G is a simple and robust linear Constant Current Regulator (CCR) 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 25% of regulation with only 0.5V Vak. 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 commercial signage applications.
Wide operating voltage range
Immediate turn-ON
Voltage surge suppressing - Protecting LEDs
SBT (self-biased transistor) technology
High or low-side control, simple battery charge, reduce LED binning and therefore inventory, no EMI
