General Description

1.0V to 1.6V supply voltage  
DC to AC conversion  
The Supertex HV824 is a high voltage driver designed to drive EL  
lampswithcapacitiveloadsof2nFto15nF. Theinputsupplyvoltage  
range is 1.0V to1.6V. The device uses a single inductor and a  
minimum number of passive components. Typical output voltage  
applied to the EL lamp is 120V to 150V peak-to-peak. The HV824  
can be enabled/disabled by connecting the RSW resistor to

Adjustable output lamp frequency to control lamp color,  
lamp life, and power consumption  
enables the IC when it is at logic low.  
Adjustable converter frequency to eliminate harmonics and  
optimize power consumption  
The HV824 has two internal oscillators, a switching MOSFET, and  
a high voltage EL lamp driver. The frequency for the switching  
MOSFET is set by an external resistor connected between the  
Rsw-osc pin and the VDD pin. The ELlamp driver frequency is set by  
an external resistor connected between the REL-osc pin and the VDD  
pin. AnexternalinductorisconnectedbetweentheLx 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.

Low current draw under no load condition  
Applications  
Pagers  
The switching MOSFET charges the external inductor and dis-  
charges it into the 0.01µF to 0.1µF capacitor at Cs. The voltage at  
CS will start to increase. Once the voltage at Cs reaches a nominal  
value of 75V, the switching MOSFET is turned OFF to conserve  
power. The outputs VA and VB are configured as an H-bridge and  
are switching in opposite states to achieve a maximum voltage of  
180V peak-to-peak across the EL lamp.
