Description: Low Input Voltage/ 180VPP Output Voltage/ EL Driver

Features

* 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

Applications

* The MIC4827 converts a low voltage DC input to a 180VPP AC output signal that drives the EL lamp. The MIC4827 is comprised of two stages: a boost stage, and an H-bridge, lamp driver, stage. The boost stage steps the input voltage up to +90V. The H-bridge stage then alternately switches the +90V out
