HV823

Supertex inc. HV823 High Voltage EL Lamp Driver IC Features General Description ►► Processed with HVCMOS® technology The Supertex HV823 is a high-voltage driver designed for driving EL ►► 2.0 to 9.5V operating supply voltage lamps of up to 50nF. EL lamps greater than 50nF can be driven for ►► DC to AC conversion applications not requiring high brightness. The input supply voltage ►► 180V peak-to-peak typical output voltage ►► Large output load capability typically 50nF ►► Permits the use of high-resistance elastomeric lamp components ►► Adjustable output lamp frequency to control range is from 2.0V to 9.5V. 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 ±90V. The chip can be enabled by connecting the resistors on the RSW-Osc pin and the REL-Osc pin to the VDD pin, and disabled when connected to GND. lamp color, lamp life, and power consumption...
