Linear LED Drivers eliminate need for external components.August 14, 2007 -
Occupying 3 x 3 mm board space, 2-channel SP7120 and 3-channel SP7122 multichannel drivers feature channel-to-channel matching of 0.8% typical with 3% absolute current accuracy. Drivers are factory programmed in fixed 15, 20, or 25 mA current outputs which are designated by an A, B, or C, respectively, in part number suffix. Available in Pb-free SPT 23-6 package, devices are specified over -40 to +85°C temperature range.

Zero External Components Required by Sipex's New LED Driver Family
A complete solution in a 3mm x 3mm space
MILPITAS, Calif., July 19 / / -- Sipex Corporation (NASDAQ:SIPX) today announced the release of the SP7120 family of multi-channel, linear LED Drivers. The family was created to minimize the board space and simplify designs required to drive LED display backlight by eliminating all required external components. The family currently includes the two-channel SP7120 and the three-channel SP7122. The devices are factory programmed in fixed 15mA, 20mA, or 25mA current outputs which are designated by an A, B, or C, respectively, in the suffix of the part number. Customers order the output options based upon their backlight current requirements.
Eliminating the external components reduces board space, critical in today's ever shrinking designs. The entire Sipex driver solution requires an area of only 3mm x 3mm. Channel-to-channel matching is improved to a 0.8% (typical) with a 3% absolute current accuracy, versus competitive solutions of 2% (typical) matching and 7% absolute accuracy, ensuring the best light uniformity which is critical in the backlighting of small displays.
"This family of LED drivers delivers minimal board space and simplicity which are two critical attributes mobile phone designers are always seeking," said Chris Lee, technical marketing manager. "Sipex is committed to providing product solutions that support the latest LED technology and applications while addressing system requirements."
"Sipex continues to expand our LED Driver portfolio by solving complex problems seen in LED backlighting. Customers can now choose from highly integrated solutions such as the SP7680, the high current SP6682, and now the space saving and simple SP7120 Family", said Ed Lam, vice president of marketing for Sipex.
Pricing and Availability
The SP7120 and SP7122 are available in a Pb-free SOT 23-6 package. They are specified over the -40 degrees C to 85 degrees C temperature range. Pricing for both devices begins at $0.35 in 1,000 piece quantities. Data sheets and additional information on this family, and other Sipex products, can be found at http://www.sipex.com/.
