LED Drivers for LED Backlights Backlight LED Driver for Small LCD Panels (Charge Pump Type) BD1606MVV ● Description The multi-level brightness control white LED driver not only ensures efficient boost by automatically changing the boost rate but also works as a constant current driver in 64 steps, so that the driving current can be adjusted finely. This IC is best suited to turn on white LEDs that require high-accuracy LED brightness control. ● Features 1) A 6 parallel LED driver is mounted 2) 64-step LED current adjust function 3) Inter-LED relative current accuracy: 3% or less 4) LED individual lighting/dimming control via a I 2C BUS interface 5) Automatic transition charge pump type DC/DC converter (×1,×1.5 and ×2) 6) High efficiency achieved (90% or more at maximum) 7) Various protection functions such as output voltage protection, overcurrent limiter and thermal shutdown circuit are mounted. 8) Small QFN package ● Applications This driver is applicable for various fields such as mobile phones, portable game machines and white goods. ● Absolute Maximum Rating (Ta=25℃) Parameter Symbol Limits Unit Power supply voltage VMAX 7 V Operating temperature range Topr -30 ~ +85 ℃ Storage temperature range Tstg -55 ~ +150 ℃ Power dissipation Pd 780 (*1) mW (*1) When a glass epoxy substrate (70mm × 70mm × 1.6mm) has been mounted, this loss will decrease 6.2mW/℃ if Ta is higher than or equal to 25℃. ● Recommended Operation Range (Ta=-30℃ to +85℃) Parameter Symbol Limits Unit Operating power supply voltage VCC 2.7~5.5 V No.11040EAT24 |
