LED flash driver from NXP

NXP has unveiled its Solid State Lighting (SSL) portfolio targeted at the mobile flash, CE, automotive lighting and general lighting markets.

Enhanced picture quality
The first product in this new line is the NXP UBA3001, a camera-phone LED flash driver that promises the maximum flash light output at the highest efficiency from a battery-operated mobile handset. The increased flash performance enhances picture quality in poor lighting conditions, enabling an improved visual experience.

The UBA3001 promises above 90 percent efficiency across the entire battery voltage range, delivering maximum flash light from a small footprint and with only five low-value external components. The device delivers 1A to a single high-brightness LED and enables great flash performance regardless of the battery charge, thanks to its automatic voltage up- and down-conversion. The solution has been designed specifically for demanding camera phones, offering dedicated features such as lower current during transmit mode, automatic switch-off, LED true switch-off and full control of current settings for different uses including flash, torch and "camera/video-on" indicator modes.

Exciting opportunity
"The promise of SSL solutions to revolutionize the performance and efficiency of lighting represents a very exciting opportunity for manufacturers and consumers alike. Light is a sensory experience and, with our new product range, NXP will deliver vibrant solutions for SSL applications," said Edgar Langen, general manager for SSL, NXP. "By establishing a dedicated business team for advancing SSL technology, we are proud to show our commitment to the market."

The NXP UBA3001 LED flash driver is available for customer evaluation.
