Features  
General Description  
Processed with HVCMOS® technology  
2.4V to 9.5V operating supply voltage  
DC to AC conversion  
TheSupertexHV803isahigh-voltagedriverdesignedfordriving  
EL lamps of up to 30nF. EL lamps greater than 30nF can be  
driven for applications not requiring high brightness. The input  
supplyvoltagerangeisfrom2.4to9.5V.Thedeviceusesasingle  
inductor and a minimum number of passive components. The  
nominal regulated output voltage that is applied to the EL lamp  
is ±90V. The chip can be enabled by connecting the resistors on  
RSW-osc and REL-osc to VDD and disabled when connected to GND.  
180V peak-to-peak typical output voltage  
Large output load capability typically 30nF  
Short circuit protection on outputs  
Adjustable output lamp frequency to control lamp color,  
lamp life, and power consumption  
The HV803 has two internal oscillators, a switching MOSFET,  
and a high-voltage EL lamp driver. The frequency for the switch-  
ing converter MOSFET 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 be-  
tween REL-osc pin and the VDD pin. An external inductor is  
connected between the Lx and VDD pins. A 0.01µF to 0.1µF  
capacitor is connected between CS and GND pins. The EL lamp  
is connected between VA and VB pins.  
Adjustable converter frequency to eliminate harmonics and  
optimize power consumption  
Enable/disable function  
Low current draw under no load condition  
The switching MOSFET charges the external inductor and  
discharges it into the Cs capacitor. The voltage at Cs will start to  
increase. Once the voltage at Cs reaches a nominal value of 90V,  
the switching MOSFET is turned OFF to conserve power. The  
outputs VA and VB are configured as an H-bridge and are  
switchedinoppositestatestoachieve180Vpeak-to-peakacross
