Si3404-A-GM Image

The Si3404-A-GM from Skyworks Solutions is a Fully-Integrated Power-Over-Ethernet Controller that has been designed for voice-over IP telephones, wireless access points, security and surveillance IP cameras, point-of-sale terminals, internet appliances, and network device applications. It integrates the necessary power management and control functions required in a power-over-ethernet (PoE) power delivery (PD) application. This PoE controller requires a DC supply of 1.5 - 57 V and a supply current of up to 5 mA. It benefits from an optimized architecture that minimizes the solution footprint and external BOM cost and enables the use of low-cost external components while maintaining high performance. This PoE integrates a transient surge suppressor, a switching power FET, and an integrated, current mode controlled switching regulator that supports isolated or non-isolated flyback and buck converter topologies. It supports the IEEE 802.3at specification for Type 1, single-event classification. This RoHS-compliant PoE controller is available in a surface-mount package that measures 4 x 4 mm.
