Overview
DESCRIPTION The BL8584 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 BL8584 is suitable for applications such as portable device display and keypad backlighting.
There are six identical channels in BL8584, each of which can drive one LED by current rating of 20mA.
BL8584 is available with QFN 3X3-16 package TYPICAL APPLICATION BL8584 6-Channels WLED Linear Driver FEATURES • 6-channels output • 2.
7 to 5.
5V input range • PWM dimming control • LED sink current of 20mA • Independent current sink circuit for each LED output • Low standby current • High accuracy current match on each channel APPLICATIONS • LCD screen backlights driver • Mobile phone, portable device keypad backlights driver PIN ASSIGNMENT BL8584 BLOCK DIAGRAM www.
