General Description
The Supertex HV8051 and HV8053 are high-voltage drivers
designed for driving EL lamps of typically 4nF and 12nF for a 1V
and 3V operation. The input supply voltage range is from 1.0V to
1.6V for HV8051 and 2.4V to 3.5V for HV8053. The device uses
a single inductor and a minimum number of passive components.
Typical output voltage that can be applied to the EL lamp is
±
50V
for HV8051 and
±
70V for HV8053.
The HV8051/HV8053 has two internal oscillators, a switching
bipolar junction transistor (BJT), and a high-voltage EL lamp
driver. The frequency for the switching BJT is set by an external
resistor connected between the R
sw-osc
pin and the supply pin
V
DD
. The EL lamp driver frequency is set by an external resistor
connected between R
EL-osc
pin and the V
DD
pin. An external
inductor is connected between the L
x
and V
DD
pins. A 0.1
μ
F
capacitor is connected between C
s
and GND pins. The EL lamp
is connected between V
A
and V
B
pins.
The switching BJT charges the external inductor and discharges
it into the 0.1
μ
F capacitor at C
s
. The voltage at C
s
will start to
increase. The outputs V
A
and V
B
are configured as an H bridge
and are switching in opposite states to achieve a peak-to-peak
voltage of two times the V
CS
voltage across the EL lamp.
