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 µSOIC packages.
