Intersil Unveils Initial Product Offering for White LED Market

-- New Elantec™ EL7513 step-up regulator drives up to 12 LEDs while ensuring uniform brightness in white LED backlighting applications

MILPITAS, CA, December 10, 2002 – Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high performance analog and wireless networking solutions, today unveiled the first device in a new family of products for white Light Emitting Diode (LED) displays that provides the precision, accuracy and efficiency required in cell phones, personal digital assistants (PDAs), digital cameras and other battery-powered electronics. Intersil’s new EL7513 is a high frequency pulse width modulation (PWM) step-up regulator capable of driving up to 12 LEDs while ensuring uniform brightness in white LED backlighting applications.

“New generations of portable products use color displays that depend on white LED backlighting to ensure brilliance and color accuracy. Our EL7513 white LED regulator is tailored to the demanding performance and low power requirements of these products,” said Michael Jennings, director of strategic marketing for Intersil’s Elantec video and flat panel products. “This new PWM step-up converter is specially designed to boost maximum output voltage in order to drive four LEDs in series or 12 LEDs in a series/parallel configuration, ensuring uniform brightness across white LED backlit screens.

EL7513 Technical Description
The EL7513 is a high-frequency boost converter designed specifically for driving white LEDs. With the ability to boost up to 18 volts, the EL7513 features soft-start and dimming control, offers ±4% LED diode current accuracy and can achieve up to 89% efficiency when driving a 30 mA load. The device operates from 2.6 volts to 5.5 volts and features a standby mode of just 1 mA maximum.

Intersil’s EL7513 represents the first in a new series of Elantec products targeted at white LED applications including PDAs, cellular phones, digital cameras, camcorders and portable games. Intersil will be introducing additional white LED products while offering complementary Elantec video products such as gamma buffers, VCOM amplifiers, DC/DC converters and programmable buffers.
