SP4480 - Dual Electroluminscent Lamp Driver

General 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.

Key Features

  • a low power standby mode which draws less than 1µA (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 VDD and VSS.
