BD2606MVV

General Description

Key Specifications

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.
