■ DESCRIPTOIN

The

BL8580/1

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 BL8580/1

is suitable for applications such as portable

device display and keypad backlighting.

In

portable

application,

three

or

four-channel LED solutions are popular.

BL8580 has three LED channels with a

SOT-23-6 package. BL8581 has four LED

channels with a SOP-8 package.
