Kinetic Technologies Releases Highly Efficient, 13W Powered Device and DC-DC Controller for Power over Ethernet (PoE) Solutions

/in /by

San Jose, Calif. January 5, 2017 – Kinetic Technologies, a high-performance analog and mixed-signal semiconductor company focused on developing power management solutions for computing, consumer, industrial, and communications markets, today introduced the AS1114, a single chip, highly integrated power solution targeted at 13W PoE, Powered Devices, requiring high efficiency and small size.  The AS1114 is specifically designed to fully support IEEE Std. 802.3at Type 1 PDs, and enables customers to bring to market higher performance products including VoIP phones, IP security cameras and wireless LAN access points. The innovative silicon solution, built on standard HV CMOS technology, includes system-level circuitry for lower EMI emissions and robust surge protection, in addition to the PD controller functionality.

The AS1114 combines rectification and protection circuitry with a PD controller and a DC-DC controller. This high level of integration provides significant reliability and protection advantages, as well as simplifying the PoE PD design. The device provides seamless support for local power and over temperature protection.

The AS1114 also provides advanced power management through integration of a hot-swap switch and a DC-DC controller that operates from a switched input voltage and includes soft-start and current limiting functions. The DC-DC architecture is a current mode converter, which can be configured with external component changes for either fly-backor buck topologies to support non-isolated or isolated switching topologies.  The device is designed to provide a safe low impedance discharge paths directly back to the earth ground, resulting in superior reliability and circuit protection.

The AS1114 includes a series of platform tested circuit capabilities to assist system designers in providing solutions that meet or exceed the current regulatory and extreme environmental usages.

The AS1114 is a highly integrated PD product that addresses the needs of the high growth PoE market,” said Fred Greenfeld, Applications Director at Kinetic Technologies. A key requirement of PoE systems is immunity to overvoltage and surge events. The AS1114 is unique in addressing EMI and surge resilience, and by integrating the diode bridge and protection circuitry, it significantly increases the reaction time of protection devices and PHY immunity to over-voltage stress events. Integrating these components also substantially reduces board-to-board variation and increases overall manufacturability, providing the customer with time to market advantage, while saving overall system cost and maximizing system efficiency.”

The AS1114 is supplied in a QFN55-20, RoHS and Green Compliant package and is rated over the -40 degree C to +85 degree C industrial temperature range.
