Dual EL Drivers Reduce Noise

Aug. 8, 2006
The HV843 and HV845 rely on patented technology to significantly reduce audible noise and feature independent input control for lamp selection and 180 Vp-p output voltages. They are designed to drive two EL lamps with a combined area of 3.5 square

The HV843 and HV845 rely on patented technology to significantly reduce audible noise and feature independent input control for lamp selection and 180 Vp-p output voltages. They are designed to drive two EL lamps with a combined area of 3.5 square inches from input supply voltages ranging from 2V to 5.8V. Both devices use a single inductor in conjunction with a minimal number of passive components. The HV845 also has two independent common output pins that further minimize dc offset in a 2-segment EL lamp. The HV843 is available in an MLP/DFN-10 package (HV835K7-G) and HV845 in an MLP/QFN-12 (HV845K7-G). Both are green and RoHS compliant. Prices are $1.08 and 1.12 each/1,000, respectively.
