PS4508 40V, 120mA Single Channel Linear LED Driver Features  Adjustable output current LED driver  Support digital and analog dimming control  Maximum 120mA output current regulator  Wide supply voltage ranges from 4.5V to 40V  ±4% output current accuracy Confidential  Lowquiescentcurrent  Thermal protect: Current ramp down 3.3%/℃  RoHS Compliant and Halogen Free General Description PS4508 is a single channel LED driver with adjustable output current. The output current typically ranges from 10mA to 120mA through external current setting resistor (REXT pin). To achieve no flick feature with analog dimming control, the set output current is linearly controlled by dimming control (PDIM pin) ranging from 0.25V to 3V.
