Features  
General Description  
❏ 1.8V to 3.5V operating supply voltage  
The Supertex HV826 is a high voltage driver designed for driving  
EL lamps. The input supply voltage range is from 1.8V to 3.5V.  
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 80V. The chip can be enabled/  
disabled by connecting the resistor on RSW-OSC to VDD/ground.  
❏ DC to AC conversion  
❏ Adjustable output frequency  
❏ Adjustable switch frequency  
❏ Output voltage regulation  
❏ Enable/disable function  
The HV826 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 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 0.01-0.1µF capacitor  
is connected between CS and ground.The EL lamp is connected  
between VA and VB.  
Applications  
❏ Mobile cellular phones  
❏ Pagers  
The switching MOSFET charges the external inductor and  
discharges it into the capacitor at CS.The voltage at CS will start  
to increase. Once the voltage at CS reaches a nominal value of  
80V, 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 160V peak-to-peak  
across the EL lamp.  
❏ Portable Transceivers  
❏ Remote Control Units  
❏ Calculators
