Adjustable Constant Current
Regulator & LED Driver
50 V, 150 − 350 mA + 10%, 4.2 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
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 14% of regulation with
only 0.5 V Vak. The R
adj
pin allows I
reg(SS)
to be adjusted to higher
currents by attaching a resistor between R
adj
(Pin 3) and the Cathode
(Pin 4). The R
adj
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 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.
