Adjustable Constant Current
Regulator & LED Driver
45 V, 20 − 40 mA + 15%, 1.
5 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 (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 20% of regulation with only 0.
5 V Vak.
The Radj pin allows Ireg(SS) to be adjusted to higher currents by...
