ROHM BD2606MVV-E2 LED Driver IC, 2.7 → 5.5 V 120mA 16-Pin SQFN016V4040

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.

A 4 to 6 parallel LED driver is mounted
64-step LED current adjust function
Inter-LED relative current accuracy: 3% or less
LED individual lighting/dimming control via an I²C BUS interface
Automatic transition charge pump type DC/DC converter (1x, 1.5x, 2x)
High efficiency achieved (90% or more at maximum)
Output voltage protection
Over current protection
Thermal shutdown (TSD)
