The MIC4830YMM is a low noise 180Vp-p electroluminescent lamp (EL) Driver uses advanced bipolar, CMOS, DMOS (BCD) technology. The MIC4830 integrates a high voltage boost converter and an H-bridge driver for driving a large EL lamp. The MIC4830 can drive large panel displays for mobile phones, multimedia players or automotive electronics where EL panels are used for backlighting. The MIC4830 offers design flexibility with adjustable lamp and boost converter frequencies, simply by applying external resistors. A new H-Bridge design reduces audible noise by creating smoother AC voltage across the EL panel.
- Low audible noise EL drive waveform
- Supports EL panel sizes up to 4in2
- Small inductor size with low profile
- Adjustable boost converter frequency
- Adjustable EL lamp frequency
