Tri-EL Lamp Driver IC

The Supertex HV858 is a high voltage triple EL lamp driver 2 2 designed for driving combined EL lamps of up to 3.0in (1.0in each). The input supply voltage range is from 1.8V to 6.5V. The device is designed such that the input voltage to the inductor CAN be different from the input voltage to the device (split supply). 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 95V. The HV858 has two internal Oscillators one for the internal switching MOSFET and the other for the high voltage EL lamp driver. The EL lamp frequency is , xed internally at 500Hz. The power converter Oscillator runs 256 times faster than the EL lamp driver at 128kHz. By Supertex, Inc.
