[ Product description ]

BD6184GUL is “Intelligent LED Driver” that is the most suitable for the cellular phone. It has 3~8LED driver and output variable LDO4ch for LCD Backlight. It can be developed widely from the High End model to the Low End model. As it has charge pump circuit for LED power supply, it is no need to use coils, and it contributes to small space.
VCSP50L3(3.15mm x 3.10mm×0.55mm)
It adopts the very thin CSP package that is the most suitable for the slim phone.
