high power LED drivers demonstrate innovative solutions for industry

This device is also particularly suitable for small to medium size LCD backlighting applications with a better than 3% channel to channel matching ensuring a uniform display brightness. Parallel implementation of several devices on the same I2C bus is possible in order to drive and control larger banks of LEDs for larger size LCD displays.Visual indicators and improved display readability requirements are becoming more prevalent in portable and handheld devices to maximize the user experience," said Eric Pittana, director of marketing for Exar's Power Management Product Line. "The XRP7620 enables designers to achieve true white light for improved screen resolution or any color of light by means of simple software settings. The XRP7620 represents true creativity and customization at your finger tips."

Operating from a single cell lithium-ion battery or fixed 3.3V or 5V rails and supporting an industry standard 2-line I2C serial interface, each channel can be programmed up to a current of 31.5mA in steps of 500 microamp. Selective channel enabling and diming as well as overall configuration is achieved through a set of 5 internal registers. A specific shutdown mode allows the device to retain the previously loaded configuration - operational and current programming - in order to be reused again when needed.Highly reliable, accurate, power management is a critical part of any technology system.
