Mouser stocks Silicon Labs’ PoE+ family for high wattage IoT use

Targeting Voice over IP (VoIP), motor positioned IP, security cameras and other industrial, feature-rich IoT devices, the Si3406x Power over Ethernet Plus (PoE+) powered device family from Silicon Labs is now available from Mouser Electronics.

The devices integrate all necessary high-voltage discrete components on a single PD chip, says Mouser, and are designed to reduce time to market and system cost for a variety of high-efficiency, high-power POE+ PD applications. The ICs deliver 30W of power to support feature-rich IoT products to meet demand for high-wattage IoT devices that support the POE+ standard.

The Silicon Labs Si3406x POE+ PD family ICs convert the high voltage supplied over Ethernet copper cabling into a regulated, low-voltage DC supply. The ICs offer reduced EMI, flexible power conversion options, a robust sleep mode augmented with mode control, wake pin, and LED driver, and IEEE 802.3at compliance.

The Si3406x POE+ PD family includes the flagship Si3406 IC as well as the Si34061 variant, which adds support for external FETs and to improve power conversion efficiency. The family’s Si34062 variant includes support for sleep modes with wake function, as well as LED drive capability.

The 20-pin Si3406 IC and 24-pin Si34061 and Si34062 are housed in a compact, 5.0 x 5.0mm QFN package, and support an operating temperature range of -40 to +85 degrees C.

Three evaluation boards, also available from Mouser Electronics, support the new devices. The tiny, 32 x 32mm, 7W Class 2 Si3406FBC2-KIT and the compact, 15W Class 3 Si3406FBC3-KIT showcase non-isolated flyback designs, while the 30W, 90 per cent efficient Si34061ISOC4-KIT highlights a high-power, isolated flyback using the Si34061. All three evaluation boards include detailed design guides and EMI test reports.

Mouser claims to stock the world’s widest selection of the latest semiconductors and electronic components for the newest design projects. Its website is continually updated and offers advanced search methods to help customers quickly locate inventory. also houses data sheets, supplier-specific reference designs, application notes, technical design information, and engineering tools.

Silicon Labs provides silicon and software for the IoT, Internet infrastructure, industrial automation, consumer, and automotive markets.
