HV859  
Initial Release  
High Voltage EL Lamp Driver for Low Noise Applications  
Features  
General Description  
ꢀ Patented audible noise reduction  
ꢀ Patented lamp aging compensation  
ꢀ 210 VPP output voltage for higher brightness  
ꢀ Patented output timing for high efficiency  
ꢀ Single cell lithium ion compatible  
ꢀ 150nA shutdown current  
ꢀ Wide input voltage range 1.8V to 5.0V  
ꢀ Separately adjustable lamp and converter  
frequencies  
ꢀ Output voltage regulation  
ꢀ Split supply capability  
The Supertex HV859 is a high voltage driver designed for  
driving Electroluminescent (EL) lamps of up to 5 square  
inches. The input supply voltage range is from 1.8V to 5.0V.  
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 105V. The chip can be  
enabled/disabled by connecting the resistor on RSW-OSC to VDD/  
ground.  
The HV859 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 R  
pin and the supply pin VDD. The EL lamp  
driver frequenScWy-OiSsC set by an external resistor connected  
Applications  
ꢀ LCD backlighting  
ꢀ Mobile Cellular Phone keypads  
ꢀ PDAs  
ꢀ Handheld wireless communication products  
ꢀ Global Positioning Systems (GPS)  
between R  
pin and the VDD pin. An external inductor is  
connected EbLe-OtSwCeen the L and VDD pins or VIN for split supply  
applications. A 0.003-0.1XµF capacitor is connected between  
C and ground. The EL lamp is connected between VA and  
VBS.  
The switching MOSFET charges the external inductor and  
discharges it into the capacitor at CS. The voltage at C will start  
to increase. Once the voltage at CS reaches a nomiSnal value  
of 105V, the switching MOSFET is turned OFF to conserve  
power. The outputs VA and V are configured as an H bridge  
and are switching in oppositeBstates to achieve 105V across  
the EL lamp.
