Adjustable Constant Current Regulator & LED Driver
45 V, 90 − 160 mA + 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.
The CCR is based on patent- pending 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 Ra...
