Akros Silicon SoC supports 60W and 90W PoE applications

EDN met with Akros Vice President of Marketing, James Ashe at APEC 2013. We discussed this digital isolation technology which ranges from 2kV to 4 kV and enables SoC integration in bulk CMOS. I was quite intrigued with this feisty, creative and innovative company. Keep a close eye on them, there is some good talent there, led by some really good board member leadership with proven electronics and semiconductor track records.

Akros Silicon Inc. developed the AS1860, the newest member of the company۪s GreenEdge family of system-on-a-chip (SoC) energy management ICs. The IC is equipped with Akros۪ proprietary GreenEdge digital isolation technology and is suited to support deployments of 60W and above Power over Ethernet (PoE) Powered Device (PD) applications such as thin clients, monitors, industrial Ethernet, IPTV, building management, Industrial Networking and many other high power designs.

GreenEdgeTM technology

F1x600

This single-package solution offers high efficiency and reliability as well as low system costs and board real estate.

F2x600

Significant board footprint reductions are achieved by the Akros SoC

The solution SoC offers the following features:

  • Dynamic power-level adjustment (to 60W and above) without using opto-couplers and their associated complex compensation networks
  • Higher power conversion efficiency due to communication across the isolation barrier
  • More accurate output-voltage sensing using a resistor-divider sensor on the secondary side

F3x600

A high level of integration of the full PoE solution is achieved by the Akros architecture on SoC

Other existing approaches to higher power (60W and above) PoE deployments require multiple components, such as two or three power management ICs, several opto-couplers and custom transformers. In addition to adding component cost, consuming board space and increasing design complexity, these approaches are vulnerable to shoot-through issues and losses due to rectifier diode and reverse recovery. Akros۪ approach can accommodate 60W and above PoE applications using just two components: one AS1860 SoC and one external FET. Moreover, by integrating GreenEdge digital isolation, the AS1860 enables the implementation of many advanced diagnostic and high-voltage telemetry features that allow operators to remotely manage power, which in turn enhances reliability and energy efficiency.

60W and above PoE deployments are coming soon and are expected to transform next-generation enterprise workspaces.

Broadcom, a global innovator and leader in semiconductor solutions for wired and wireless communications, has a family of PoE PSE (Power Sourcing Equipment) controllers (model BCM59111) that supports the rapidly emerging 60 W application re-quirements.

Akros۪ GreenEdge technology, integrated into a family of PoE system-on-a-chip (SoC) energy management ICs, allows high-speed digital communication across an integrated isolation barrier. The technology provides necessary hand-shaking and telemetry information with the power source to allow for safe and con-trolled power transfer, while eliminating optocouplers and their associated complex compensation networks.  The result is improvement in reliability, reduced real estate, unmatched efficiency in power conversion and more accurate output-voltage sensing. Additionally, this technology enables system-level cost reduction.

Broadcom۪s PoE solutions claim to be the most flexible and scalable solutions on the market.  The BCM59111 is a highly integrated PSE solution offering world-class thermal performance.  The adoption of PoE in the market continues to grow as more devices are connected to the network.  Expanding to 60W will allow even more devices to be connected.

“The AS18xx family of GreenEdge energy management SoCs, introduced in 2009, has established itself as a leading solution in PoE applications adopted by major OEMs worldwide,” said Parviz Ghaffaripour, Akros Silicon۪s President & CEO. “The AS1860 is in full production and offers field-proven technology designed to immediately support the 60 W requirements. Our flagship digital isolation technology, GreenEdge, allows digital communication, power control and health monitoring across the isolation barrier. These features accommodate flexibility within systems to create robust power management, while eliminating long-term reliability concerns related to optocouplers.”

PoE technology provides DC power from Power Sourcing Equipment (PSE) over twisted pair Ethernet cables to Powered Devices (PDs) within enterprise, small business or home networks. The PoE standard has evolved from 13 W (IEEE 802.3af) to 30 W (IEEE 802.3at) and now the industry is rapidly moving to 60 W of power per switch port. The 60 W requirement is driven by the need to support applications such as thin clients, monitors, industrial Ethernet, IPTV, building management and lighting control systems, nurse call systems in hospitals, point-of-sale terminals and other higher power applications. The move to 60W PoE will allow deployment of PoE-enabled PDs into new markets while facilitating easier, more energy-efficient power management across the entire enterprise.
