Overview

IMP52 7 POWER MANAGEMENT Single Cell Battery Powered Electroluminescent Lamp Driver/Inverter The IMP527 is an Electroluminescent (EL) lamp driver designed for systems that must operate down to 1 volt and below.
The input supply voltage range is 0.
9V to 2.
5V.
Typical output lamp drive voltage is 180V.
All four EL lamp-driving functions are on-chip.
These are the switchmode 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...
