BD1754HFN
Constant Current LED Driver with 64 Dimming Steps for up to 4 LEDs

The multi-level brightness control LED works as a constant current driver in 64 steps, so that the driving current can be adjusted finely. BD1754HFN is best suited to turn on LEDs that require high-accuracy LED brightness control.
