GENERAL DESCRIPTION
A highly efficient charge pump enables LED driving over full Li-Ion battery voltage range. The AS3668 maintains excellent efficiency over a wide operating range by automatically selecting the best charge pump gain based on the LED forward voltage requirements and the device input voltage. Furthermore the chip supports an automatic power-save mode which gets active when LED outputs are not active. The special powersave mode has a extremely low current consumption below 10μA (typ.).the AS3668 has an I2C-compatible control interface which supports two slave address without having a dedicated address selection pin. For fancy lighting effects synchronized with an audio signal the device supports special digital filter modes in order to make music literally visible on the 4 independent configurable current sources. The AS3668 is available in a very tiny 12-pin WL-CSP (1.255x1.680mm) 0.4mm pitch package. Figure 1. AS3668 Block Diagram 2 KeyFEATURES
