A8280
8-CH LED BACKLIGHT DRIVER
WLED LINEAR DRIVER
DESCRIPTION
FEATURES
The A8280 is a CMOS based White/Blue LED driver 8-channel output
with stand-alone capability. The driver is primarily 2.7 to 5.5V input range
designed for LED backlighting of LCD display PWM dimming control, suggested 1KHz
powered by Li-ion battery. With its high efficiency, LED sink current of 20mA
low standby current and wide range of input supply Independent current sink circuit for each LED
voltage, the A8280 is suitable for applications such
output
as portable device display and keypad backlighting. Low standby current
There are eight identical channels in A8280, each of High accuracy current match on each channel
which can drive one LED by current rating of 20mA. Available in QFN16(3x3) Package
The A8280 is available in QFN16(3x3) package.
