The MIC4830 is a low noise 180VPP electroluminescent (EL) lamp driver. Using 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, MP3 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.The MIC4830 is offered in 3mm x 3mm MLF? and MSOP-8 Pb-free and RoHS-compliant packaging with a -40°C to 85°C junction temperature range.

mic認證與telec認證介紹 無線產(chǎn)品在各國都有著嚴格的管控法規(guī)標準，在中國有srrc認證，美國有fcc-id，韓國的kcc認證等等，而在日本針對無線產(chǎn)品的認證是telec認證，有人又稱之為mic
高通的QCC304x及后續(xù)的芯片支持HybridANC，包含F(xiàn)FMIC和FBMIC。其中FFMIC可以與2-CVC中的副MIC共用同一個MIC，可以是數(shù)字MIC或者模擬MIC。但是如果是模擬MIC的話，因為ANC與CVC會共用FFMIC的模擬增益。
