Micrel's MIC4826 is a high output voltage, DC to AC converter, designed for driving electroluminescent (EL) lamps. The device operates from an input voltage range of 1.8V to 5.5V, making it suitable for 1-cell Li-Ion and 2- or 3-cell alkaline/NiCad/NiMH battery applications. The MIC4826 converts a low voltage DC input to a 160VPP AC output signal that drives the EL lamp. The MIC4826 is comprised of two stages: a boost stage, and an H-bridge, lamp driver stage. The boost stage steps the input voltage up to
