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 device features an internal feedback loop that regulates the lamp voltage  
output to 160VPP (typical) with varying supply voltages to maintain constant EL lamp brightness  
over the life of the battery. The device also has a low power shutdown mode which draws less  
than 50nA (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 set the internal  
oscillator frequency. The SP4405 is ideal for portable applications such as pagers, cellular  
phones, PDAs, and other portable applications using LCDs in dim or low light environments.  
The SP4405 is offered in 8-pin SOIC and 8-pin µSOIC packages.
