Micrel Semiconductor (San Jose, CA) announced its new electro-luminescent lamp driver ICs, the MIC4826 and MIC4827. Applications include LCD panels and keypads used in cellular phones, PDAs, pagers and remote controls.
The MIC4826/7 ICs converts a 1.8V to 5.5V dc input voltage to a high-voltage ac signal. The MIC4826 generates a 160V and the MIC4827 generates a 180V peak-to-peak ac-output voltage. Their 1.8V to 5.5V input-voltage ranges make the MIC4826/7 capable of operating directly from two-cell alkaline/NiCd/NiMH batteries or one-cell lithium-ion batteries.
The MIC4826/7 are housed in a small MSOP-8 package and require only six external passive components. The MIC4826BMM and MIC4827BMM are available in the MSOP-8 package. The MIC4826 is priced at $1.18, and the MIC4827 is priced at $1.28 when purchased in 1,000-piece quantities. Samples are available from stock and production quantities are stock to 12 weeks ARO.
