MIC4834  
Low Noise Dual 220 VPP EL Driver  
General Description  
Features  
•
Drives two EL panels, up to 3 in2 each at full  
brightness  
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 battery applications.

•
–40oC to +125oC junction temperature range  
The MIC4834 features separate oscillators for the boost  
and H-bridge stages. The boost frequency may be  
adjusted with an external resistor to optimize efficiency  
and brightness. The H-bridge frequency is internally preset  
to 225Hz, to reduce the number of external components  
and layout space.  
Applications

Mobile phones  
MP3/portable media players (PMP)  
Clocks/ watches  
Remote controls  
Cordless phones  
GPS devices  
The MIC4834 is available in 10 pin 3mmx3mm MLF®  
package as well as MSOP-10L, and has an operating  
junction temperature range of –40°C to +125°C.
