Integrated LED drivers need no support
Multichannel linear LED drivers minimise board space and simplify display backlighting by requiring no external components.
Sipex Corp has designed its new family of multichannel linear LED drivers to minimise 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

LED driver powers LCD backlights
Low-side LED driver is ideal for powering small and mid-size LCD modules that use LEDs for backlighting.
Advanced 5V transceivers for RS-485 networks
A family of advanced 5V RS-485 transceivers has 15kV ESD protection, hot-swap capability, advanced failsafe protection, voltage and thermal overload protection, and shutdown.
The devices are factory programmed in fixed 15, 20 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 on 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 3 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", says 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", says Ed Lam, Vice President of Marketing for Sipex.
The SP7120 and SP7122 are available in a Pb-free SOT 23-6 package.
They are specified over the -40 to +85C temperature range.
Pricing for both devices begins at US $0.35 in 1000-piece quantities.
