BL8088

DESCRIPTION The BL8088 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 BL8088 is suitable for applications such as portable device display and keypad backlighting. There are eight identical channels in BL8088, each of which can drive one LED by current rating of 20mA. BL8088 is available with QFN 3X3-16 package TYPICAL APPLICATION Vin VIN 1uF D1 EN BLC8109888 EN D2 D3 D4 D5 GND D6 D8 D7 BLOCK DIAGRAM BL8088 8-Channel WLED Linear Driver FEATURES  8-channel output  2.7 to 5.5V input range  PWM dimming control, suggested 1KHz  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 NC NC NC EN 16 15 14 13 1 12 2 11 3 10 49 5678 NC NC VIN KD GND LLNYW D8 D1 D7 D2 D6 D5 D4 D3 www.belling.com.cn 1 BL8088 MARKING INFORMATION Product Classification Marking BL8088CJKTR NC NC NC EN 16 15 14 13 1 12 2 11 3 10 49 5678 KC: Product Code KC LLNYW LL: LOT No. N: FAB Code Y: Year No. W: Week No. NC VIN D8 D7 KD LLNYW NC GND D1 D2 D6 D5 D4 D3 Top view ORDERING INFORMATION BL8088 □1 □2 □3 Code □1 □2 □3 Description Temperature & Rohs: C: -40~85C, P...
