• Manufacturer Part Number: IMP803/D1
• Description: HIGH-VOLTAGE EL LAMP DRIVER
• Manufacturer: IMP [IMP, Inc]

Test and Application Circut, 6.0V
At higher input voltage levels, the IMP803 will drive large EL
lamps. Figure 3 shows a 6.0V circuit configuration that will drive
a 10 square-inch lamp.
