Next Generation El Lamp Driver Offers Higher Brightness, Dimming and Lower Noise



HV860 Features Patent-Pending Technology For Highly Efficient Operation

SUNNYVALE, Calif., February 28, 2006 - Supertex, Inc. (NASDAQ: SUPX), a
recognized leader in high voltage analog and mixed signal integrated circuits (ICs),
today 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 MLP-12 package (HV860K7-G). The part is Green
and 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.
