LED Drivers for LCD Backlights Backlight LED Driver for Small LCD Panels (Charge Pump Type) BD1601MUV ● 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) Built-in parallel LED driver for 4 to 6 lamps. 2) 64-step LED current adjust function. 3) Inter-LED relative current accuracy: 3% or less 4) Lighting/dimming control via a single-line digital control 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, over current 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 Ratings (Ta=25℃) Parameter Symbol Ratings Unit Power supply voltage VMAX 7 V Operating temperature range Topr -30 ~ +85 ℃ Storage temperature range Tstg -55 ~ +150 ℃ Power dissipation Pd 700 (*1) mW (*1) When a glass epoxy substrate (70mm × 70mm × 1.6mm) has been mounted, this loss will decrease 5.6mW/℃ if Ta is higher than or equal to 25℃. ● Operating Conditions (Ta = -30 ~ 85℃) Parameter Symbol Ratings Unit Operating power supply voltage VCC 2.7~5.5 V No.11040EBT22 |
