Key Features

Single Cell Battery Powered

Electroluminescent Lamp

Driver/Inverter

ꢀ Wide operating voltage range - from 0.9V to 2.5V

ꢀ Simple design requires few passive components

ꢀ 180V peak-to-peak typical AC output voltage

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 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.

ꢀ Adjustable output frequency controls lamp

color and power consumption

ꢀ Adjustable converter frequency minimizes

circuit power consumption

ꢀ Disable mode extends battery life

ꢀ Disable current 1µA typical

The circuit requires few external components; one inductor, one diode,

one capacitor and two resistors. The resistors set the frequency for the

two oscillators.

ꢀ Compact MicroSO package option

A disable mode puts the chip into a low current-drain state. When dis-

abled, quiescent current drops to 1µA typical with a V_DDof 1.5V. The chip

can be disabled by connecting R_SW, the oscillator frequency setting resis-

tor, to ground. A disable pad (active low), accessible only on the die, can

also be used to disable the driver.

Applications

ꢀ Audio/TV remote control units

ꢀ Pagers/Cellular phones

ꢀ PDAs

An internal circuit shuts down the switching regulator when the lamp

drive voltage exceeds 180V peak-to-peak. This conserves power and

extends battery life.

ꢀ Clocks and radios

ꢀ Portable GPS receivers

ꢀ LCD modules

The IMP527 is available in MicroSO and SO-8 packages and in die form.
