MIC4826
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 160V PP 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. The H-bridge stage then alternately
switches the +80V output to each terminal of the EL lamp,
thus creating a 160V PP AC signal to drive the EL lamp and
generate light.
The MIC4826 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.
