Low Voltage Electroluminescent Lamp Driver with Regulated Output Voltage

DESCRIPTION The SP4405 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 SP4405 will operate from a +2.2V to +4.5V battery source. ■

The A4405 is an automotive power management IC that uses a high frequency constant on-time 5.45 V pre-regulator to supply two internal 5 V linear regulators and a 3.3 V linear DMOS driver.
