Adjustable Constant Current
Regulator & LED Driver
45 V, 20 − 40 mA + 15%, 1.5 W Package
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.
only 0.5 V Vak. The R
currents by attaching a resistor between R
(Pin 4). The R
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 Automotive,
Industrial and Commercial Signage applications. This device is
available in a thermally robust package and is qualified to stringent
AEC−Q101 standard, which is lead-free RoHS compliant and uses
halogen-free molding compound.
