Applications
An LED driver IC that generates voltages necessary
for driving high-intensity LEDs through booster DC/DC converters,
and is able to drive all of the LEDs in a cell-phone with the single chip.
Features
- Constant current driving LED driver for composite multiple support
I.e.) Four main lights+two sub lights＋four flash lights+RGB - High current driving (SW regulator power source) Load current maximum 500mA supported
- High efficiency (through/LED terminal feedback mode supported)
- Reduced peripheral devices (charge pump power supply)
- Miniaturized package (4×4mm/3.5×3.5mm/2.6×2.6mm)
- High value added function mounted (including gradation function)
