Product Summary

The HV803LG is a high-voltage driver designed for driving EL lamps of up to 30nF. EL lamps greater than 30nF can be driven for applications not requiring high brightness. The input supply voltage range is from 2.4 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 applications of the HV803LG include Pagers, Cellular phones, Electronic personal organizers, GPS units, Handheld personal computers, Portable instrumentation.
