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
