Intersil’s Switched-Capacitor Voltage Inverter Delivers Voltage Conversion for Hand-Held, Battery Powered Applications

— Targets liquid crystal display applications
— Performs positive to negative voltage conversion

IRVINE, Calif, July 6, 2000 — Intersil (NASDAQ: ISIL) today introduced its latest switched-capacitor voltage inverter addressing the need for high power efficiency and low operating current in today’s battery powered, hand-held integrated communications products. The ICL828 specifically targets liquid crystal display (LCD) applications such as cell phones, pagers and personal digital assistants (PDAs).

"The device combines high power efficiency with low operating current," said Tom Bogut, product marketing manager at Intersil. "The resulting low power consumption translates into extended battery life for end user applications. This device is a key component of wireless, hand-held communications tools and facilitates the visual component of converging communications technologies."

Intersil’s ICL828 integrated circuit (IC) contains all the required circuitry to complete a negative converter. It performs supply voltage conversions from positive to negative. The resulting negative voltage can then be utilized by LCD applications. Also referred to as a "charge pump," the ICL828 supports an input supply voltage range of +1.5V to +5.5V and yields complimentary output voltages of –1.5V to –5.5V. The device utilizes two external polarized electrolytic capacitors that can also be reconfigured to double the supply voltage. Cascading the device also increases voltage output.

The device operates within the temperature range of –40 degrees Celsius to 85 degrees Celsius. A small outline package conserves board space and meets the compact size requirements of hand-held devices. The ICL828 also features greater than 95 percent efficiency and low operating current, making the device ideal for both battery-powered and board-level voltage conversion applications.

Pricing, Packaging and Availability
The ICL828 is immediately available in a five pin SOT23-5 package at a cost of $0.60 in 1,000 piece quantities. For more information about the ICL828, visit Intersil’s Web site at www.intersil.com, or call 1-888-INTERSIL ext. 7990.
