... Die HV803LG HV803X General Description The Supertex HV803 is a high-voltage driver designed for driving EL lamps 30nF. EL lamps greater than 30nF can be driven for applications not requiring high brightness. The input supply voltage range is from 2.4 to 9.5V. The device uses a single inductor and a minimum number of passive components. The nominal regulated output voltage that is applied to the EL lamp is ± ...

... EL lamp. The input power, (V dissipation of the package (350mW), an external resistor in series with one side of the lamp is recommended to help reduce the package power dissipation. Enable/Disable Configuration The HV803 can be easily enabled and disabled via a logic control signal on the R and R resistors as shown in Figure 4 below. ...
