White LED Driver IC

The SM8133B is a Charge Pump type White LED Driver It CAN drive 1 to 6 backlight white LED connected in parallel and 1 ash white LED The output voltage circuit has a 3.0V LDO (Low Dropout Regulator), making the device ideal for camera-equipped cellular phones. The Charge Pump switches between 1 to 1.5 boost mode in response to LED drive current requirements to extend battery life to the maximum. The boost switch- ing occurs in response to the drive current of all the connected LED and thus supports variations in LED for- ward-bias voltage drop (VF). Each LED drive current is controlled by a 7-channel LED drive current control circuit. The 6 backlight channels CAN be subdivided into 2 groups, with each group having independent dim- ming and lighting control. The backlight grouping, backlight LED drive current and ON/OFF control, ash LED drive current and ON/OFF control, and LDO output ON/OFF control are all set by 3-wire serial Interface data input. Also, the RESETB pin CAN be connected to the Microcontroller supply for a system-wide shutdown function. By Nippon Precision Circuits Inc, (NPC)
