Sipex Introduces Single Wire Programmable Charge Pump LED Flash Driver in 2x3 DFN8

2.4MHz operating frequency, charge pump architecture, and small package optimizes device for smallest programmable solution

MILPITAS, Calif., April 3 / -- Sipex Corporation today announced the release of the SP7686, a single wire dynamically programmable charge pump LED flash driver capable of driving up to 500mA. This device simplifies the design of multi-condition LED lighting when used for mobile phone camera flash, torch, pre-flash mode, and any portable LED lighting applications.

Operating at an industry leading 2.4MHz switching frequency, the SP7686 requires only four small external components further reducing the overall solution footprint to new levels. SP7686 features a typical 3.5 second timeout in Flash mode which prevents the LED from over-heating during long operating duty cycles. The programmable LED current also allows designers to reduce currents as the battery gets low to prevent false system resets thus extending useful battery life.

The family also includes the SP7686A which eliminates the single wire interface but provides two separate control pins for enable and Torch/Flash select. The Flash current is preset to 400mA, and the torch current is set to 150mA. These LED Flash Drivers enable a wide range of LED lighting applications with minimum external components require and completely effortless design in today's application. Both products offered in a tiny 2mm x 3mm DFN package making them the smallest single wire control LED drivers on the market today.

"SP7686 delivers the smallest solution size, design simplicity, and programmable LED current making the SP7686 and SP7686A an excellent choice for cell phone designers and others engineers using LED lighting", said Chris Lee, Technical Marketing Manager. "Sipex is committed to providing product solutions and features that support the latest LED technology."

Pricing and Availability

SP7686 and SP7686A are available in a Pb-free, thermally enhanced 8-pin 2x3mm DFN package and is specified over the -40 degrees C to +85 degrees C temperature range. Pricing for these products begins at $1.25 in 1,000 piece quantities.
