... REL-Osc * Enable is available in die form only. General Description The Supertex HV823 is a high-voltage driver designed for driv- ing EL lamps 50nF. EL lamps greater than 50nF can be driven for applications not requiring high brightness. The input supply voltage range is from 2.0V to 9.5V. The device uses a single inductor and a minimum number of passive components ...
