"New generations of portable products use colour displays that depend on white LED backlighting to ensure brilliance and colour 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 convertor 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.
The EL7513 is a high-frequency boost convertor designed specifically for driving white LEDs.
With the ability to boost up to 18V, the EL7513 features soft-start and dimming control, offers 4% LED diode current accuracy and can achieve up to 89% efficiency when driving a 30mA load.
The device operates from 2.6 to 5.5V, and features a standby mode of just 1A maximum.
