MIC4826 - Low Input Voltage/ 160VPP Output Voltage/ EL Driver

Description

Micrel’s MIC4826 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.

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 MIC4826 uses a single inductor and a minimum number of external components, making it ideal for portable, spacesensitive.

MIC4826 Micrel MIC4826 Low Input Voltage, 160VPP Output Voltage, EL Driver Final Information General Description Micrel’s MIC4826 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 MIC4826 converts a low voltage DC input to a 160VPP AC output signal that drives the EL lamp. The MIC4826 is comprised of two stages: a boost stage, and an H-bridge, lamp driver, stage. The boost stage steps the input voltage up to +80V.
