The NCR405U from Nexperia is an Automotive Qualified LED Driver IC that is ideal for constant current LED drivers, generic constant current sources, and automotive applications. It requires an input voltage of 40 V. This LED driver has been designed with a resistor-equipped PNP-type transistor with two diodes on one chip in a plastic package. It provides an output current of 50 mA which can be adjusted up to 65 mA using an external resistor, thereby resulting in a high current accuracy even under variations in supply voltages. It has a reduced component count and board space, making it suitable for space-constrained applications. This AEC-Q101-qualified LED Driver IC is available in a surface-mount package that measures 3.1 x 3 mm.
