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.
Features
■ 6-Ch Parallel LED Driver
■ 64-Step LED Current Adjust Function
■ Inter-LED Relative Current Accuracy: 3% or less
■ LED Individual Lighting/Dimming Control via I2C
BUS Interface
■ Automatic Transition Charge Pump Type DC/DC
Converter (x1, x1.5 and x2)
■ High Efficiency (90% or More at Maximum)
■ Various Protection Functions such as Output
Voltage Protection, Over-Current Limiter and
Thermal Shutdown Circuit
Applications
This driver is applicable for various fields such as
mobile phones, portable game machines and white LED
products.

(Note 1) When mounted on a glass epoxy substrate (70mm x 70mm x 1.6mm), derate by 6.2mW/°C for Ta is higher than 25°C.
Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open
circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures such as adding a fuse, in case the IC is
operated over the absolute maximum ratings.
