Datasheet
6-Channel Charge Pump
White LED Driver
with 64 Dimming Steps and I²C Compatible Interface
BD2606MVV
General Description
BD2606MVV is a multi-level brightness control white
LED driver that not only ensures efficient boost by
automatically changing the boost rate but also works as
a constant current driver with 64 steps, so that the
driving current can be adjusted finely. This IC is best
suited to turn ON white LEDs that require high-accuracy
LED brightness control.
