DESCRIPTION
The SP4480 provides a designer with two electroluminescent lamp drivers for backlighting
solutions. The EL lamp outputs operate in opposite phase so he SP4480 device can be easily
implemented into applications driving two EL lamps simultaneously or driving double-sided,
multi-color EL lamps. The integration of a dual EL lamp driver in a cost-effective single IC
reduces component count and board space requirements. The SP4480 is ideal for portable
applications such as cellular phones, pagers, PDAs, medical equipment, and other designs
with liquid crystal displays, keypads, and backlit readouts. The SP4480
operates from a
+2.2V to +6.0V source. The device features a low power standby mode which draws less than
1
μ
A (maximum). The frequency of the internal oscillator is set with a single external resistor.
A single inductor is required to generate the high voltage AC outputs to drive the EL lamps.
All input pins are ESD protected with internal diodes to V
