BD6592MUV 
[ Product description ]
They are white LED driver IC with PWM step-up DC / DC converter and current driver. The wide and precision brightness can be controlled by external PWM pulse. They have very accurate current drivers, and it has few current errors between each strings. So, it will be helpful to reduce brightness spots on the LCD. Small package type is suited for saving space.
