Off-Line, High Voltage EL Lamp Driver Features Processed with HVCMOS technology Input voltage up to 200V DC 400V peak-to-peak output voltage Output load up to 30nF (00in 2 for 3.nF/in 2 lamp) djustable output lamp frequency djustable on/off pulsing frequency pplications Electronic organizers Handheld portable computers Display signs Portable instrumentation equipment General Description The Supertex is an off-line, high voltage, EL lamp driver integrated circuit designed for driving EL lamps of up to 30nF at 400Hz. The input supply voltage can be a rectified nominal 20V C source or any other DC source up to 200V. The will supply the EL lamp with an C square wave with a peak-to-peak voltage of two times the input DC voltage. The has two internal oscillators, a low voltage output linear regulator, and a high voltage output H-bridge. The high voltage output H-bridge frequency is set by an external resistor connected between the and pins. The EL lamp is connected between pins V and. For the in the -pin package, an external RC network can be connected between the oscillator s Osc and pins to pulse the EL lamp on and off.
