LED Drivers for LED Backlights
Backlight LED Driver
for Small LCD Panels (Charge Pump Type)
BD1606MVV
No.11040EAT24
●Description
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. This IC is best
suited to turn on white LEDs that require high-accuracy LED brightness control.
●Features
1) A 6 parallel LED driver is mounted
2) 64-step LED current adjust function
3) Inter-LED relative current accuracy: 3% or less
4) LED individual lighting/dimming control via a I²C BUS interface
5) Automatic transition charge pump type DC/DC converter (×1,×1.5 and ×2)
6) High efficiency achieved (90% or more at maximum)
7) Various protection functions such as output voltage protection, overcurrent limiter and thermal shutdown circuit are mounted.
8) Small QFN package
●Applications
This driver is applicable for various fields such as mobile phones, portable game machines and white goods.
