The MIC4826 and MIC4827 are high voltage EL (Electroluminescent) drivers designed for driving EL lamps of up to 6 in2 (typically). The input supply voltage range is from 1.8V to 5.5V, making both devices suitable for one-cell Li-Ion and two-cell NiCad/NiMH/Alkaline applications. Both devices use a single inductor and a minimum number of passive components. The nominal AC output voltage that is applied to the EL lamp is 160V for the MIC4826 and 180V for MIC4827. The chip can be enabled or disabled by connecting the resistor on RSW and REL to VDD or ground, respectively.
