HV8051 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 Rsw-osc pin and the supply pin VDD. The EL lamp driver frequency is set by an external resistor connected between REL-osc pin and the VDD pin. An external inductor is connected between the Lx and VDD pins. A 0.1F capacitor is connected between Cs and GND pins. The EL lamp is connected between VA and VB pins.
The switching BJT charges the external inductor and discharges it into the 0.1F capacitor at Cs. The voltage at Cs will start to increase. The outputs VA and VB are configured as an H bridge and are switching in opposite states to achieve a peak-to-peak voltage of two times the VCS voltage across the EL lamp.
