The 3 Bank SP7680 LED Driver Maximizes Flexibility for Multiple
Backlighting Configurations
MILPITAS, Calif., June 26 /PRNewswire-FirstCall/ -- Sipex Corporation
(Nasdaq: SIPX) today announced the release of the SP7680, a seven channel,
charge-pump based, Light Management Unit (LMU) designed for mobile display
and keypad LED backlighting.
The SP7680 is targeted at backlighting the main display, sub-display,
and indicator functions. Seven LED driver channels are partitioned into
three banks of four channels, two channels and one channel; however, the
LEDs can be configured in numerous combinations to meet the needs of
various lighting requirements. Each bank can be independently programmed
through an I2C interface up to 31mA (63mA for the single channel bank) with
6-bit resolution.
The SP7680 charge pump has gains of both 1x and 1.5x and, along with a
driver dropout voltage of 0.2V, maximizes efficiency and extends the
minimum input voltage range. The device operates at 2MHz, utilizes only 4
small capacitors and is offered in a 3x3mm QFN16 package, requiring minimum
board space.
"The SP7680, with its unique three bank LED driver design, delivers the
ultimate flexibility in solving a wide variety of backlighting requirements
making it an excellent choice for designers working across multiple design
platforms," said Chris Lee, technical marketing manager for power products
at Sipex.
"This product is an excellent example of Sipex's focus on more
proprietary, higher integration, system level solutions to drive more value
for our customers," said Ed Lam, Vice President of Marketing for Sipex. "We
have had excellent customer response to the functionality the SP7680 offers
in mobile applications."

QFN package, and it is specified over the -40DegreesC to +85DegreesC
