Advance Information

High Voltage EL Lamp Driver

Features

General Description

❑ Processed with HVCMOS^®technology

The Supertex HV829A/B are high voltage EL lamp driver inte-

grated circuits designed for driving EL lamps of up to 70nF at

1000Hz. The input supply voltage range is from 2.7V to 5.5V.

These devices use a single inductor, a high voltage switching

FET and a minimum number of passive components. The

HV829A/B will supply the EL lamp with an AC square wave with

a peak-to-peak voltage of two times the set regulated DC

voltage.

❑ V_DDvoltage range = 2.7 to 5.5V DC

❑ Output load up to 70nF (20 in²for 3.5nF/ in²lamp)

❑ Adjustable DC-DC converter frequency

❑ Continious output voltage regulation control

(from 50V to 200V)

The HV829A/B has one internal oscillator and a high voltage EL

lamp driver. The frequency for the external switching MOSFET

is set by an external resistor connected between the R_SW-oscpin

and GND. The EL frequency for the HV829A is equal to the

switchingfrequencydividedby64wheretheELfrequencyforthe

HV829B is equal to the switching frequency divided by 128. Gate

of the external MOSFET is connected to the Gate pin. An

external inductor is connected between the Drain of external

MOSFET and V_DDpin. A 0.01-2.5µF capacitor is connected

between Cs and ground. The EL lamp is connected between V_A

and V_B. The output voltage regulation level is controlled via the

V_REGpin for dimming and/or conservation of power. The output

voltage regulation can be controlled continuously between 50V

and 200V depending on the voltage applied to V_REGpin (0.75V

to 3V).

Application

❑ Electronic Organizers

❑ Handheld Portable Computers

❑ Display Signs

❑ Portable Instrumentation Equipment

The switching MOSFET charges the external inductor and

discharges it into the capacitor at C_S. The voltage at C_Swill start

to increase. Once the voltage at C_Sreaches a nominal value

chosen by the user, the switching MOSFET is turned OFF to

conserve power. The outputs V_Aand V_Bare configured as an H

bridge and are switching in opposite states to achieve the AC

voltage of +/- VREG voltage across the EL lamp.
