Overview

IMP525 POWER MANAGEMENT Single Cell Battery Powered Electroluminescent Lamp Driver/Inverter The IMP525 is an Electroluminescent (EL) lamp driver designed for systems that must operate below 1 volt.
The input supply voltage range is 0.
9V to 2.
5V.
Typical output lamp drive voltage is 112V.
All four EL lampdriving functions are on-chip.
These are the switch-mode power supply, its high-frequency oscillator, the high-voltage H-bridge lamp driver and its low-frequency oscillator.
EL lamps of up to 6nF capacitance can be driven to high brightness.
The circuit requires few external components; one inductor, one diode, one capacitor and two resistors.
The resistors set the frequency for the two osci...
