SP4490 - Two Panel Electroluminscent Lamp Driver

General Description

The SP4490 electroluminescent lamp driver provides designers of cell phones PDA's and other handheld, portable electronic devices with an integrated solution for driving two EL lamps independently.

Key Features

  • a low power standby mode which draws less than 1µA. The frequency of the internal oscillator is set using a single external resistor. A single external 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.
