General Description  
TheSupertexHV825isahighvoltagedriverdesignedfordriving  
EL lamps typically up to 6nF. The input supply voltage range  
is from 1.0V to 1.6V. The device uses a single inductor and a  
minimum number of passive components. The typical output  
voltage that can be applied to the EL lamp is 56V.  
The HV825 can be enabled/disabled by connecting the RSW-Osc  
resistor to VDD/GND.  
The HV825 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 VDD  
supply pin. 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 0.01 to 0.1µF, 100V capacitor is connected between the CS  
pin and the GND pin. The EL lamp is connected between the  
VA pin and the VBpin.

it into the 0.01 to 0.1µF, 100V capacitor at the CS pin. The volt-  
age at the CS pin 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.
