MIC4834 Low Noise Dual 220 VPP EL Driver

The MIC4834 is a low noise dual Electroluminescent (EL) Panel driver used in backlighting applications. The MIC4834 converts a low DC voltage to a high DC voltage using a boost converter and then alternates the high DC voltage across the EL panels using an H-bridge. The MIC4834 incorporates internal.

MIC4834 Features

* an operating input voltage range of 2.3V to 5.8V, making it suitable for 1-cell Li-ion and 2- or 3-cell alkaline/NiCad/NiMH battery applications. The MIC4834 features separate oscillators for the boost and H-bridge stages. The boost frequency may be adjusted with an external resistor to optimize eff
