LED DRVR 3Segment 3.3V/5V 12-Pin UCSP T/R

BD82103GWL is charge pump type 2 light or 3 light parallel LED driver for the portable instruments. This IC not only ensures efficient boost by automatically changing the boost rate but also works as a constant current driver in 16 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.

• 2 light or 3 light parallel LED driver is mounted
• 16-step LED current adjust function
• Inter-LED relative current accuracy: 5% or less
• Driving control via a single-line digital control interface
• Automatic transition charge pump type DC/DC converter (x1, x1.5, x2)
• High efficiency achieved (Maximum over 93%)
• It transits for the most suitable power operating by the LED terminal process of the 3rd light when 2 light driving
• Various protection functions such as output voltage protection and thermal shutdown circuit are mounted.
