Supertex Introduces New, Lower Noise Versions of Single and Dual Segment EL Lamp Drivers



SUNNYVALE, Calif., June 16, 2006 - Supertex, Inc. (NASDAQ: SUPX), a recognized leader in high voltage analog and mixed signal integrated circuits (ICs), today introduced the HV835 and the HV857L, two low noise electroluminescent (EL) lamp drivers designed to drive EL lamps for handheld devices such as mobile phones, PDAs, global positioning systems, and other handheld wireless products.

The HV835 is a dual segment EL lamp driver that features independent input control for lamp selection, peak-to-peak output of 160V, and a wide input supply range of 2.0V to 5.8V. The IC is ideal for driving two EL lamps with a combined area of 3.5 square inches.

The HV857L is a high voltage driver designed to drive a single EL lamp of up to 5 square inches. It is a lower noise, pin compatible replacement for the existing HV857 part. The IC features patented circuitry for reduced audible noise, peak-to-peak output of 190V for higher lamp brightness, and patented output timing for high efficiency.

"The introduction of these two EL lamp drivers gives users the ability to significantly reduce system noise," states Ahmed Masood, Vice President of Marketing for Supertex. "These ICs are pin compatible, drop-in replacements for our existing single and dual segment EL lamp drivers with little or no modification to existing application circuits."

The HV835 is available in an MLP/DFN-10 package (HV835K7-G). The HV857L is available in MSOP-8 and MLP/DFN-8 packages (HV857LMG-G and HV857LK7-G, respectively). All parts are Green and RoHS compliant. Samples are available from stock. Lead-time for production quantities is 4-6 weeks ARO. Pricing is US$1.08 each for the HV835K7-G, US$0.88 each for the HV857LMG-G, and US$0.90 each for the HV857LK7-G, all in 1K quantities.
