MIC4834 Low Noise Dual 220 VPP EL Driver General Description 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 wave-shaping circuitry specifically designed to reduce audible noise emitted by EL panels.
With only one inductor the MIC4834 can drive two outputs and requires a minimum number of passive components.
It 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 ...
