HV839

High Voltage Dual EL Lamp Driver

Features

General Description

The Supertex HV839 is a high voltage driver designed

for driving two EL lamps with a combined area of 3.5

square inches. The input supply voltage range is from

2.0V to 5.8V. The device is designed to reduce the

amount of audible noise emitted by the lamp. This

device uses a single inductor and minimum number of

passive components to drive two EL lamps. The

nominal regulated output voltage of ±90V is applied to

the EL lamps. The two EL lamps can be turned ON

and OFF by the two logic input control pins, C₁and

C₂. The device is disabled when both C₁and C₂

(pins 1 and 4) are at logic low.

ꢀ

Independent input control for lamp selection

Split supply capability

Patented output timing

One miniature inductor to power both lamps

Low shutdown current

Wide input voltage range 2.0V to 5.8V

Output voltage regulation

No SCR output

Available in small packages (10-lead MSOP and

10-lead DFN/MLP)

Applications

The HV839 has an internal oscillator, a switching

MOSFET, and two high voltage EL lamp drivers. An

external resistor connected between the R_SW-OSCpin

and the voltage supply pin V_DDsets the frequency for

the switching MOSFET. The EL lamp driver frequency

is set by dividing the MOSFET switching frequency by

128. An external inductor is connected between the

L_Xand the V_DDpins. Depending on the EL lamp size,

a 1.0 to 10.0nF, 100V capacitor is connected between

C_Sand Ground. The two EL lamps are connected

between EL₁to Com and EL₂to Com. The switching

MOSFET charges the external inductor and

discharges it into the capacitor at C_S. The voltage at

C_Sincreases. Once the voltage at C_Sreaches a

nominal value of 90V, the switching MOSFET is

turned OFF to conserve power. The outputs EL₁to

Com and EL₂to Com are configured as H bridges and

switch in opposite states to achieve 180V across the

EL lamp.
