Регуляторы тока светодиодных ламп NSI45060JDT4G

Драйвер светодиода , 1 выход, постоянный ток, 45В (Vin), 100мА, TO-252-3

The NSI45060JDT4G is a simple and robust adjustable Constant Current Regulator 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 20% of regulation with only 0.5V 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 anode-cathode voltage rating withstands surges common in commercial signage applications.
