Design Kit Reduces Time, Cost of PoE PD Development

SAN JOSE, Calif.--(BUSINESS WIRE)--May 30, 2006--Power Integrations (Nasdaq:POWI ), the leader in high-voltage analog integrated circuits for power conversion, today introduced a new reference design kit for Power-over-Ethernet (PoE) Powered Devices (PDs). The rapid growth of the PoE PD market -- expanding at a compounded annual growth rate of almost 36 percent (Venture Development Corporation, June 2005) -- is being driven by the wide adoption of network appliances, wireless LANs and Voice over Internet Protocol (VoIP) telephones. Power Integrations has addressed the needs of this high-growth market by providing a reference design to help speed prototyping and delivery of standards-compliant PoE PDs. The reference design combines a multi-class PoE interface and DC-DC switching circuit built around the company's monolithic DPA-Switch® family of ICs.

"Our new PoE reference design kit offers an excellent solution for reducing time-to-market of PoE PDs," said Andrew Smith, DC-DC product marketing manager for Power Integrations. "The circuit design is fully compliant with the IEEE 802.3af standard for PoE PDs, and early adopters are finding that it offers a highly effective, low-cost solution to jumpstart their network appliance designs."

The reference design kit supports the design of all current classes of PoE PDs (Class 0 to Class 3) and a power range up to 12.95 W. A designer can change the class of a design by replacing a single resistor. The design carries out PoE signature and classification functions, while the integrated DPA-Switch device manages all the primary DC-DC switching and control functions. The complete circuit requires only 16 components and costs about one-third less than designs based on integrated PoE interface/controller ICs.

The PI circuit design was tested by the University of New Hampshire Interoperability Consortium (UNH-IOC) using a comprehensive suite of power sending equipment (PSE), and was shown to meet IEEE 802.3af requirements in all cases. Copies of the UNH-IOC test reports, along with additional information on Power Integrations' PoE offerings and complete information on the DPA-Switch family of ICs, can be found on the Power Integrations website at www.powerint.com/poe.htm.

Available Today

The PoE Class 2 PD Reference Design Kit (DAK-86) is available today from PI and its authorized distributors. Pricing is USD 100. The design kit contains a 3.3 V, 2 A Class 2 power supply, samples of the DPA-Switch family and design software plus a comprehensive engineering report including a circuit description and schematic, test results and transformer design information.
