Key Features

High-Voltage EL Lamp Driver

The IMP803 is an Electroluminescent (EL) lamp driver with the four EL

lamp driving functions on-chip. These are the switch-mode power sup-

ply, its high-frequency oscillator, the high-voltage H-bridge lamp driver

and its low-frequency oscillator. The IMP803 drives EL lamps of up to

30nF capacitance to high brightness; EL lamps with capacitances greater

than 30nF can be driven, but will be lower in light output. The typical

regulated output voltage that is applied to the EL lamp is 180V peak-to-

peak. The circuit requires few external components, a single inductor,

single diode, two capacitors and three resistors. Two of these resistors

set the frequency for two internal oscillators.

ꢀ Low Power: 420µA typical V_DDcurrent

ꢀ Wide operating voltage range - from 2.0V to 6.5V

ꢀ 180V peak-to-peak typical AC output voltage

ꢀ Large output load capability - drive lamps

with more than 30nF capacitance

ꢀ Adjustable output lamp frequency for control of

lamp color, lamp life, and power consumption

ꢀ Adjustable converter frequency to minimize

power consumption

The IMP803 operates over a 2.0V to 6.5V supply voltage range. A

regulated, low-power source can supply the low quiescent current of the

IMP803. The inductor may be driven from an independent, unregulated

supply voltage in dual supply applications.

ꢀ Device can be Enabled/Disabled

ꢀ Low quiescent current – 20nA (disabled)

ꢀ High-Voltage CMOS Process

An internal circuit shuts down the switching regulator when the lamp

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

extends battery life.

ꢀ MicroSO package option

The IMP803 is available in MicroSO and SO-8 packages and in die or

wafer form.

Applications

ꢀ GPS units/Pagers/Cellular phones

ꢀ PDAs/Handheld computers

ꢀ Safety illumination

ꢀ Portable instrumentation

ꢀ Battery-operated displays

ꢀ LCD modules
