Inductorless solutions on the rise

Everyone and everything is being streamlinedorganizational structures, production workforce and even products. It is only natural that for devices to stand out in the competition, its component count should be reduced, taking out parts that can be done without and by putting everything in just one silicon. One such approach is the inductorless solution.

According to Chris Lee, technical marketing manager for Sipex Corp.'s Power Management Products, this development is very evident today. "It's the obvious industry trend right now, this shifting from an inductor-based to an inductorless solution," he said. "And aside from cellphone camera flash, this type of solution can be used in other applications."

Daryl Nees, the company's global director for Field Area Engineers (FAEs), agrees, saying that inductorless solutions are the new trend in marketing. "In fact, we now offer ODMs, OEMs and engineers in Asia the world's smallest inductorless solutions," Nees added.

Sipex, a supplier of high performance, analog ICs, recently released its SP6686 current regulated buck/boost charge pump that delivers 400mA. The product requires no inductors and needs only three external capacitors, resulting in "reduction of the overall solution's footprint to new levels." The company now covers the 100mA to 780mA application range for camera flash. Lee disclosed that solutions at 1A and higher are presently being planned.

Other Sipex products that are targeted for release before the end of the year include dc-dc solutions that will offer efficiencies as high as 97 percent.

"We offer the fastest output startup from shutdown mode, the smallest inductorless solution, and the ability to start-up into a pre-charged load among others, that is why manufacturers of portable devices choose Sipex," Nees said.
