LED Drivers for LCD Backlights

Backlight LED Driver

for Small LCD Panels (Charge Pump Type)

No.11040EBT22

BD1601MUV

●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) Built-in parallel LED driver for 4 to 6 lamps.

2) 64-step LED current adjust function.

3) Inter-LED relative current accuracy: 3% or less

4) Lighting/dimming control via a single-line digital control 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, over current 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.
