Active-Semi Announces Latest Addition to Their Family of Power Management ICs for ARM-based Processors

Active-Semi International, Inc. Announces the Release of the ACT8937 Power Management IC for ARM-Based Processors from Samsung, Providing an Excellent Fit for Portable Applications

SAN JOSE, Calif. — (BUSINESS WIRE) — June 22, 2010 — Active-Semi International today released a new member of their patent-pending power management unit (PMU) family: the ACT8937. This device is optimized for the unique power, voltage sequencing and control requirements of advanced application processor power solutions. The new PMU device features three DC/DC step-down and four low-noise, low-dropout linear (LDO) regulators along with a complete battery-charging solution and the advanced ActivePathTM system-power selection function. The ACT8937 PMU, being released today, constitutes a complete, cost-effective and highly efficient ActivePMUTM power management solution for battery-powered mobile devices.

“The new ACT8937 highlights the latest innovation in Active-Semi's PMU products,” said Gary Hurtz, VP of Power Management at Active-Semi. “This PMU is specifically optimized for Samsung's S5PC100, S5PC110 and S5PV210 processors. The ACT8937 PMU allows the system developer to reduce the overall system BOM cost significantly by eliminating the need for external discrete components for power sequencing. The product development cycle is shortened by reducing the complexity of the software settings required for power system control.”

"The new ACT8937 PMU from Active-Semi is among the most power efficient on the market," said General Manager Mr. Ham of COWON. "With its compact design and excellent performance, it is still simple to use and to control."

“The new ACT8937 PMU is an important addition to the Active-Semi PMU product line,” said Larry Blackledge, CEO of Active-Semi. “The ACT8937 satisfies the unique power requirements of the new S5PC1xx and S5PC2xx processor families. ACT8937 is a very competitive solution for next-generation portable equipment platforms."

Active-Semi's ActivePMUTM is a patented, revolutionary technology that leverages Active-Semi's large and growing IP portfolio to produce targeted, high-performance solutions for the industry's most challenging portable power and system management problems. ActivePMUs are being deployed throughout an increasingly wide range of portable applications, from complete system management solutions for next-generation mobile communications to dedicated CPU power solutions in today's most advanced portable equipment, such as smart books, mobile devices, tablets and portable media players. Additionally, Active-Semi's ActivePSRTM family of digital Primary-Side Regulation (PSR) controllers simplify today's AC/DC designs for charger, adapter and LED lighting with low component-count, and exceed all green power efficiency or standby power standards.
