LED Drivers for LCD Backlights

Backlight LED Driver

for Small LCD Panels (Charge Pump Type)

No.11040EBT34

BD82103GWL

●Description

BD82103GWL is charge pump type 2 light or 3 light parallel LED driver for the portable instruments.

This IC not only ensures efficient boost by automatically changing the boost rate but also works as a constant current driver

in 16 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) 2light or 3light parallel LED driver is mounted

2) 16-step LED current adjust function

3) Inter-LED relative current accuracy: 5% or less

4) Driving control via a single-line digital control interface

5) Automatic transition charge pump type DC/DC converter (×1,×1.5, x2)

6) High efficiency achieved (Maximum over 93%)

7) It transits for the most suitable power operating by the LED terminal process

of the 3rd light when 2 light driving

8) Various protection functions such as output voltage protection and thermal shutdown circuit are mounted.

9) Package : UCSP50L1 (Thick 0.55mm MAX, Pin pitch 0.4mm) CSP11pin package
