BL8581A

PWM or Singl-Wire Dimming, 4-Channels WLED Linear Driver

DESCRIPTION

FEATURES

The BL8581A is a CMOS based White/Blue

LED driver with stand-alone capability. The

driver is primarily designed for LED

backlighting of LCD display powered by Li-ion

battery With its high efficiency, low standby

current and wide range of input supply

voltage, the BL8581A is suitable for

applications such as portable device display

and keypad backlighting. It can realize PWM

or single-wire dimming control through EN pin.

•

2.7 to 5.5V input range

Single-wire dimming control with linear

16- steps

•

PWM dimming control

LED sink current of max. 20mA

Independent current sink circuit for each

LED output

Low standby current

High accuracy current match on each

channel

•

BL8581A has four LED channels with MSOP-

8 or QFN 3X3 -16 package.

APPLICATIONS

•

Small Size Color LCD Backlights Driver

Mobile Phone, Portable DeviEN Keypad

Backlights Driver
