Description

This IC is white LED driver IC with PWM step-upDC/DC converter that can boost max 41V and currentdriver that can drive max 30mA. The wide andprecision brightness can be controlled by externalPWM pulse. This IC has very accurate current drivers,and it has few current errors between each strings. So,it will be helpful to reduce brightness spots on the LCDpanel. Small package is suited for saving space.
