6-Channel Charge Pump White LED Driver with 64 Dimming Steps and I²C Compatible Interface - BD2606MVV

The multi-level brightness control white LED driver not only ensures efficient boost by automatically changing the boost rate but also works as a constant current driver in 64 steps, so that the driving current can be adjusted finely. BD2606MVV is best suited to turn on white LEDs that require high-accuracy LED brightness control.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
