SP4414
DESCRIPTION
The
SP4414
is a high voltage output DC-AC inverter specifically designed to drive electrolu-
minescent lamps to backlight liquid crystal displays, keypads, and backlit readouts used in
battery operated portable equipment. The
SP4414
will operate from a +2.2V to +4.5 V battery
source. The device features a low power shutdown mode which draws less than 100nA (typical),
ideal for low power portable products. One external inductor is required to generate the high
voltage AC output. An external clock signal is used to drive the internal control signals for the
coil and EL lamp. The
SP4414
is ideal for portable applications such as pagers, cellular
phones, PDAs, and other portable applications using LCDs in dim or low light environments.
The
SP4414
is offered in 8-pin SOIC and 8-pin
μ
SOIC packages.
