MIC4827 Datasheet (Micrel Semiconductor) - Low Input Voltage/ 180VPP Output Voltage/ EL Driver

MIC4827, Low Input Voltage/ 180VPP Output Voltage/ EL Driver

Micrel’s MIC4827 is a high output voltage, DC to AC converter, designed for driving EL (Electroluminescent) lamps.

The device operates from an input voltage range of 1.8V to 5.5V, making it suitable for 1-cell Li Ion and 2- or 3-cell alkaline/NiCad/NiMH battery applications.

The MIC4827 converts a l

* separate oscillators for the boost- and H-bridge stages. External resistors independently set the operating frequency of each stage. This flexibility allows the EL lamp circuit to be optimized for maximum efficiency and brightness. The MIC4827 uses a single inductor and a minimum number of external
