EL Driver Offers Higher Brightness, Dimming and Lower Noise

Supertex, Inc. has introduced the HV860, a higher brightness, lower noise, dimmable electroluminescent (EL) lamp driver designed to light today's keypads for handheld devices such as mobile phones, PDAs, global positioning systems, and other handheld wireless communication products.

The HV860 features adjustable output regulation for dimming capability to reduce power consumption and 220V peak-to-peak output voltage for high brightness. The part is compatible with single cell lithium ion batteries and has separately adjustable lamp and converter frequencies. The HV860 features Supertex's patented lamp aging compensation technology and patented output timing for high efficiency.

"The HV860 represents the fourth generation of Supertex's proprietary EL lamp driving technology," states Ahmed Masood, Vice President of Marketing for Supertex. "This IC allows manufacturers to develop dimmable displays that can maximize the HV860's higher brightness, lower power consumption, and dramatically lower keypad noise."

The HV860 is available in a QFN-12 package (HV860K7-G). The part is RoHS compliant. Samples are available from stock. Lead-time for production quantities is 4-6 weeks ARO. Pricing is US$0.97 each for the HV860K7-G in 1K quantities.
