LED Drivers for LCD BackLights

Multifunction Backlight LED Driver

for Small LCD Panels (Charge Pump Type)

No.10040EAT16

BD6083GUL

●Description

BD6083GUL is “Intelligent LED Driver” that is the most suitable for the cellular phone.

It has 3 - 6LED driver and output variable LDO4ch for LCD Backlight.

It has ALC function that is “Low Power Consumption System” realized.

It can be developed widely from the high End model to the Low End model.

As it has charge pump circuit for DCDC, it is no need to use coils, and it contributes to small space.

VCSP50L3 (3.15mm x 3.15mm 0.5mm pitch)

It adopts the very thin CSP package that is the most suitable for the slim phone.

●Features

1) Total 3 - 6LEDs driver for LCD Backlight

・It has 4LEDs (it can select 4LED or 3LED) for exclusire use of Main and 2LEDs which can chose independent

control or a main allotment by resister setting.

・Main Group” can be controlled by Auto Luminous Control (ALC) system.

“Main Group” can be controlled by external PWM signal.

・ON/ Off and a setup of LED current are possible at the time of the independent control by the independence.

2) Ambient Light sensor interface

・Incorporates various functions such as a sensor bias adjustment function, an ADC with an average filter, a gainoffset

adjustment function and an LOG conversion function so that options can be increased for illumination intensity

sensors (Photo Diode, Photo Transistor, Photo IC (Linear/LOG)).

・Incorporates an auto gain switching function for suppressing an illumination intensity sensor current

at high illumination intensity and improving sensitivity at low illumination intensity

・Capable of customizing an LED current value according to a table setting.

・Slope control loading and an independent control change are possible.

3) Charge Pump DC/DC for LED driver

・It has x1/x1.5/ x2 mode that will be selected automatically.

・The most suitable voltage up magnification is controlled automatically by LED port voltage.

・Soft start functions、Over voltage protection (Auto-return type),Over current protection (Auto-return type) loading

4) 4ch Series Regulator (LDO)

・It has selectable output voltage by the register.(16 steps)

LDO1, LDO2, LDO3, LDO4: Iomax=150mA

5) Thermal shutdown

6) I²C BUS FS mode (max 400 kHz) Compatibility
