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 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 lowside 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
AECQ101 standard, which is lead-free RoHS compliant and uses
halogen-free molding compound, and UL94V0 certified.
