Adjustable Constant Current
Regulator & LED Driver
45 V, 35 − 70 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 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 anodecathode 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, and UL94−V0 certified.
