Constant Current Regulator & LED Driver
50 V, 350 mA +10%, 5.8 W Package
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. 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. It requires no external components allowing it to be designed as a high or low−side regulator.
