DESCRIPTION
The SP4403 is a high voltage output DC-AC inverter specifically designed to drive
electroluminescent lamps to backlight liquid crystal displays, keypads, and backlit readouts
used in battery operated portable equipment. The SP4403 will operate from a +2.2V to +4.5V
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. One external resistor is used to select the internal
oscillator frequency. The SP4403 is ideal for portable applications such as cellular phones,
PDAs, and other portable applications using LCDs in dim or low light environments. The
SP4403 is offered in 8 pin SOIC packages.
